Dual citizenship - my visa is running out soon! Help

[sirineou]

Wow, great information. Appreciated.

I speak very little Thai unfortunately, so I won't be able to communicate well with the immigration office without a translator.

I'll have someone call tomorrow to the Immigration Office and ask.

Great news for me about Canada, not needing a visa! : )

I just hope my two different last names on my two different passport won't be an issue as well lols

But I think having a dual citizenship will be great for my travels. Just need to learn a little bit more about it, as travelling alone is all new to me.

Thank you!

My wife has her married name in her US passport, and still has her Thai name in her Thai passport since we have not registered our marriage in Thailand yet,

(which we should, we have being married several years and own a couple of pieces of property in Thailand and if something happened to her, it might be a problem)

Non the less she still has her Thai name/passport,

she comes to Thailand a couple of times a year for several years now using the two passports with the different names and never had a problem.

She always carries a marriage certificate with her, in case there was a problem concerning the discrepancy.

After you get your extension of permission to stay straightened out, your trip to Canada should be no problem ;-)

1) Book your ticket using your Swedish passport details.

2) Check-in at the Thai airport using your Swedish passport, airline will understand that a Swedish citizen is entitled entry to Canada for 6 months (note that if you arriving by air from March 15, 2016, you will need a eTA).

3) Exit Thai immigration using your Thai passport.

4) Enter Canada using your Swedish passport, get 6 month permission to stay.

5) Check-in at Canadian airport using your Thai passport. If asked, show the airline your Swedish passport so that they can understand that the person checking in is the same as the person who bought the tickets (especially, as in your case your last names won't match, but all your other information should match).

6) Exit Canadian immigration using your Swedish passport.

7) Enter Thai immigration using your Thai passport.

When you book your tickets to Canada you might look to see whether you are getting a discount by booking round-trip rather than two one-way trips. If you get no discount for the round-trip, you may want to book two one-way trips instead because it eliminates the issue raised in step 5. If you do two-one way trips, then step 1, becomes

1a) Book ticket to Canada using your Swedish details.

1b) Book ticket to Thailand using your Thai passport details.

Generally, you only show one passport at a time (the one mentioned above is the proper one to show in the circumstance indicated). Only if there are questions that showing the second passport would help resolve do you show the second passport. Never give someone both passports and rely on them to figure it out for you ;-) Typically, immigration officials will only need to see one passport. Airline officials will generally only need to see one passport, except as mentioned in step 5 above and then only if you are using round-trip tickets.

Enjoy your trip to Canada. The world is your oyster, dual-national!

By the way, if you travel in South East Asia, using your Thai passport rather than Swedish one will work out better. Thais can visit many bordering countries without a visa.

Family member of a Thai (which is what you would extend as I believe) paperwork requirement is

1. Application form

2. Copy of applicant’s passport

3. Copy of documents proving relationship, such as a marriage certificate, a birth certificate, registration of child legitimization, household registration certificate, child adoption registration certificate, or other evidence from the government or relevant agency

4. Copy of evidence proving the Thai nationality of the spouse, parents, children, or adopted children, such as a national ID card, copy of household registration certificate, or other evidence issued by the government or relevant agency

All extensions are based on living location at time of application - those with upcountry registrations have been told to return there to make application but this does not appear to be set in stone as believe others have had no issues. But under current policy doing in home location has become very much the required normal procedure for all extensions as immigration has offices open in almost all provinces now.

[TerryLH]

"3) Exit Thai immigration using your Thai passport."

No. They will need to leave the country on the passport they entered on.

That clears their name in the immigration computer.

OP, when you finally do leave the country, you'll find it's not complicated. Something immigration officers are used to seeing.

I believe that the OP qualifies for an extension in her own right as a Thai citizen.

Yes, I assumed that she would be resolving the present permission to stay issue by leaving Thailand on her Swedish passport and coming back into Thailand on her Thai passport. But as that actually hasn't happened yet and may not happen, it was a bad assumption to make. It would be far better to say "exit Thailand immigration using the same passport you used to enter Thailand." Good catch, TerryLH! One must always exit a country using the same passport that was used to enter the country. I've made the correction below:

1) Book your ticket using your Swedish passport details.

2) Check-in at the Thai airport using your Swedish passport, airline will understand that a Swedish citizen is entitled entry to Canada for 6 months (note that if you arriving by air from March 15, 2016, you will need a eTA).

Phew glad that's sorted.

You seem to misunderstand - both countries will want to see entry/exit stamps. You can enter Cambodia with your Swedish passport fine but you can not then exit using the Thai passport because you would not have a legal entry on it.

Where is the problem to leave Thailand via the swedish passport, change the passport in nowhere land and come back via the thai passport.

I guess the thais who are going to a casino in the nowhere land are allowed to reenter their home country.

???

Thai people would exit and re-enter using a THAI passport.

What point are you attempting to make ? It has already been explained that it is impossible to "change passport" in no mans land .

Suggest you re read the thread.

Other than a probable argument with the Thai IO on the way back in I don't see the downside. She is Thai so they have to let her in one way or another! IMO they'd have to let her in based on her Thai ID alone.

The whole insistence on exit stamps is farcical when a Thai citizen is involved.

[mgb]

Right, a Thai is not a Farang if he use a thai passport.

You simply can forget all the rules about Farangs at the border in such circumstances.

You have a new Thai passport, I presume based on the way you talk it was issued in Thailand, so you do not have to do anything until the renewal date arrives to keep it valid for travel outside Thailand.

Also based on the way you talk you are a born in Thailand of ethnic Thai skin color and futures, this makes it simple because you just blend in with the rest of the ethic Thais. There are thousands of Thais like you with a Thai Passport. just for the sake of having a Thai Passport and/or to be a showoff.

As for the other passport, Sweden, Denmark EU, whatever that you entered Thailand on just put it away for some other day when you intend to return to Sweden, Denmark, EU or wherever you came from. Then take it to the respective embassy and tell them you have decided not to stay in Thailand but want to go back to their country. People are allowed to change their mind, it is not poured in concrete. You may tel them, granted the Thai visa is expired and didn't bother to renew because I'm living again home with my family. They will not ask you for a Thai passport because that is none of their concern, and you carefully made sure you left it at home before you departed for the embassy, out of sight out of mind.

Of course you are dealing with the EU which consistently keeps making new laws and change old ones. As happen to me an EU ethic born in Holland of centuries back Dutch ancestry. Holland read this good, did have a centuries old law that an ethic Dutch person could never loose its nationality. Well, a couple years ago without asking (referendum whatever good that does because the citizen NO ed the EU constitution but Brussels went right ahead)) the people of the country the lame heads in Den Haag nikst that law.

So when I came to the embassy I was informed I was stateloos because my expired Dutch passport under the new law could no longer be renew.

So keep this in mind.

For the time bing if I was you I would just put that farang passport away for a rainy day and then hope for the best.

I'm afraid this suggestion offers nothing that will help the OP avoid overstay status on her Swedish passport. There's something to be said for complying with immigration legalities especially when the cost of compliance is relatively low as it is in this case at this time. Because the OP is a Thai dual-national the consequences of failing to comply with the immigration legalities are less in her case than they would be for a non-Thai citizen. But some people would just like to do things the proper and legal way and avoid the need to worry about the consequences of violating the law. In this case, the cost of doing the right thing is relatively low (1,900 to obtain the extension of stay, or 2,238 to leave and come back on the Thai passport). That seems to me like a small price to pay for peace of mind.

In your case, digging a birth certificate might be of use, because the red tape cannot override constitutions, though they can make it difficult for you?

EDIT: To the OP, I'd suggest a return flight to Malaysia for the cheap. If you live near Suvarnabhumi, you'd pay around 120-200 depending on traffic for a taxi to Don Mueang, and there are tons of cheap flights to Malaysia at the moment - a couple of hundred baht difference for going upcountry versus clearing your visa status shouldn't be a cause for much of a burden

[nem0z]

Wow, you guys have been busy writing on this post, meanwhile I've been sleeping ..

Where to start ..

lopburi3; I have a copy of my birth certificate, passport, tabien baan and a Thai ID National card to present and prove that I'm Thai.

elviajero; When I entered Thailand, I wrote down my old address, Sukhumvit soi 3, which I no longer live at, on the arrival card.

sirineou; I'm glad to hear that my two different last names on my two different passport won't be a problem. It sure was when I was getting my Thai ID.

skatewash; Thank you so much for the long but detailed information about how to do my trip to Canada. I've been nervous and worried about it, but now when you've made it so simple and clear - I am no longer worried.

I'll look forward and enjoy my trip! And I'll sure have a look at the links you gave me.

And I must say I'm in total agreement with skatewash, I do not want to worry about the consequences of violating the law, and get a overstay status on my Swedish passport.

jabis; The taxi cost will be far more to Don Mueang from where I live right now hehe. I'll look at tickets today, after I'm done calling the Immigration Office. Will have a look to Malaysia, thank you!

My questions are now; If I get the extension, will I be able to work without a work permit?

If I have to fly out, do I have to stay for 1 day, or can I just stay a few hours then come back in to Thailand?

I have to fly to an International Airport right? Don't know where I heard this or who told me. Might be stupid.

Thank you guys!

[lopburi3]

1. Probably not legal by the book as you are in country as a foreign national - but do not believe it would ever come up as you have Thai ID card and that will be what employer sees and records.

2. You only have to enter/exit another country - no set time (but why not take advantage of a weekend in Malaysia - it really can be pleasant at your age).

3. Any airport having scheduled flights between countries is an international airport - what it means is there is immigration clearance facilities to allow foreigners to enter/exit.

Yes you can work. It's not a problem or illegal. You are a Thai citizen and have the same rights every other Thai has.

There's no time restriction. You can stay a few hours.

Yes you need to fly to another country (international airport.)

Your situation with immigration is purely bureaucratic. If you still live in the Bangkok area then any Bangkok address will be ok. Even if you don't I believe the extension will be very straightforward because you are Thai. Just go to the immigration office in the area of the address you want to give. Take all the proof you have that you are Thai and they will give you an extension. That extension gives you 1 year to sort out your Swedish passport issue. If necessary you can renew that 1 year extension every year indefinitely.

[nem0z]

Ok guys. I just spoke with the Immigration Office for 51 mins, here's what he said;

I can only get a 1 year extension, if my employer can give me some kind of letter to the Immigration, saying that I wish to stay and work in Thailand.

I can change my Non-B Visa into a Non-O, if I go to any Thai Embassy outside Thailand, then come back with my Swedish Passport that they've changed to Non-O, stay for another 90 days, then after that they can extend for another year.

I am not employed any longer, so that can't happen. I can go with option 2, but it will take more time and money for me to do so.

I can fly or go by land to any neighbor country, stamp out with my Swedish passport - MIGHT get a problem with Cambodia Immigration when I enter with my Thai passport because they won't see an exit stamp. But if I enter with my Swedish Passport I won't get a problem, but then when I want to enter Thailand again with my Thai Passport, I MIGHT get a problem with the Thai Immigration because they won't see an enter/exit stamp from Cambodia. IO told me that it MIGHT happen that they ask, but as far as I could understand, I'll just have to explain or show my two passport, if it comes to that. But there's no issue going by land! Same as going by air he said. Whatever is more convenient for me.

IO also told me that, if I do the extension, Immigration will probably ask me what passport I would like to use (as Thailand IO are not to keen on dual), if I then choose Thai passport, then my Swedish passport will be IINVALID!!

lopburi3; IO told me same thing ish, that I can still work since I have my Thai ID card. And yeah, no time required to spend in another country. I would love to, just walking alone around in Malaysia seems a bit too scary for me. I rather wait until I get some friends who wants to discover with me! : )

Edited August 31, 2015 by nem0z

[lopburi3]

Actually Malaysia is quite safe for daytime activities and police are quite professional. But understand would be much less stress with a travel companion. As for land crossing many people have indeed had issues in the past - Cambodia is not likely to allow entry on Thai passport without a departure stamp and if you enter on Swedish passport you will have to exit on that passport and Thai officials will likely not be happy (so be prepared to hold your ground and explain you have been advised by Bangkok immigration that there is no issue with not having an exit stamp for a Thai) .

As said previously there have been recent reports of this being allowed so with luck the officer you see or his superior will be aware.

Edited August 31, 2015 by lopburi3

[nem0z]

I'm not confident at all to do this, knowing that I'll have to explain and probably end up in an argument once I try to enter Thailand again without an exit stamp. I'll try my best though! Ain't much other to do.

[nem0z]

It seems like the best option for me now, is to try going by land to Cambodia.

So I'll take the bus from Ekkamai on Wednesday to the border. And hope for the best.

I'm afraid of what might happen if they won't let me back in to Thailand.

This whole situation has been confusing and complicated. I'm almost breaking apart ><

You simply stamp out at the thai side, change passports and take the queue to enter Thailand.

You don't have to enter Cambodia.

If a officer ask you what you are doing you simply tell him the truth.

You changed passports because you don't want to become a overstayer in your own home country.

Things are never simple with immigration it seems ;-) Some say that Thais get a break at immigration because they are Thai. Others say the opposite is true, that because Thais are not the typical customer at immigration that they often get an even higher level of scrutiny by the immigration officer than the usual foreigner. The fact that it took 51 minutes to get an answer to your questions is an indication that things at the immigration office might not be straightforward in your case.

I'm quite skeptical that things will go at the land border the way you would like and the way the immigration officer said they would. I think you can definitely exit Thailand at a land border on your Swedish passport, but I question whether you will be allowed back into Thailand on your Thai passport. I've no doubt that they would let you back in on your Swedish passport but that would defeat the whole purpose of the border run. The fact that the immigration officer said they would doesn't count for much when you're at a border dealing with a different immigration officer (who might have a different interpretation of the requirements) and who you're asking to let you into the country despite not having the proper exit stamp on your Thai passport. Certainly he could let you in, or he could decide not to do that. In any case, the decision rests with him (not the officer you talked to over the phone), and he might not be willing to "go out on a limb" and do this for you. Surely, they have to let you back into Thailand, but I think the immigration officer might take the easy way out and insist you come back on your Swedish passport. I think you can expect a discussion to ensue (in which you will be at a disadvantage if you're not a fluent Thai speaker), perhaps a lengthy discussion. I wouldn't want to put myself through that as I'm sure I would find it very stressful.

Again, my advice is to leave the country by air and re-enter Thailand on your Thai passport. This is a "normal" thing to do. It doesn't depend on convincing anyone of anything. You are a normal Swede exiting Thailand on your Swedish passport (which leaves your stay in Thailand in a proper state in immigration computers: entered as Swede, exited as Swede, didn't overstay). Then when you return, even if only a few hours later, you are a normal Thai entering Thailand on your Thai passport. In fact, you are even eligible to use the automatic gates at the airport so that you could re-enter without talking with an immigration officer, just by presenting your Thai passport.

I know which alternative I would choose. Normally I am a very frugal person and the thought of spending extra money to make a silly trip to another country would really bother me. It wouldn't in this case, and here's why: fly out and fly in and you're in the driver's seat, you control the outcome, you know how this will turn out. The other alternative relies on things out of your control. You have to rely on an immigration official to do something for you. Yes, they can do it (according to the immigration officer you talked to in Bangkok), and they should do it (according to the same officer), but on the other hand they may not do it. The uncertainty would make my mind uneasy. In this case I think it is worth the extra expense to be guaranteed of the outcome you want. Once you re-enter Thailand as a Thai (that is, having the immigration status of a Thai), all your problems and uncertainties disappear.

The outcome is in the hands of the immigration officer, and unfortunately not in the hands of the OP.

I think it's very likely that they will let you back into Thailand. I think the issue is whether they will let you re-enter on your Thai passport or insist that you re-enter on your Swedish passport. I don't think anyone can tell you which way it will go, but I don't think you'll be stranded in Cambodia.

[skatewash]

A thai citizen cannot be denied entry to Thailand. That is it.

That may be ultimately true, but I can think of many ways I would rather spend my Wednesday afternoon than discussing the finer points of that position with an immigration officer at the Cambodian border ;-)

OK, you have convinced me. Now, are you going to accompany the OP to Cambodia and convince the immigration officer there? Also, any estimate on how long it will take for the immigration officer at the Cambodian border to be convinced of this? 20 minutes? 1 hour?

mgb is absolutely right. She cannot be denied entry.

Entering Cambodia isn't necessary if she is using her Thai passport to enter Thailand and the Thai passport doesn't have an exit stamp.

If she can enter Cambodia with the Thai passport then great. If she can't then whats the point in entering Cambodia when she can just cross the road?
