I am a Singaporean considering having a tourist visa.

I am conidering too staying for about 75 days. i am ble to go to a border in this time.

however, i do not know whether with the tourist visa i am able to exit thailand at maesai and re-enter to get the extension for 30 days.

You obtain an extension of 30 days by application at an immigration office and paying 1,900 baht on a tourist visa (60 days on entry).

If you are speaking of just entry into Thailand without a visa (30 day stamp) then yes, you can obtain this on entry from Singapore and again on entry from Mai Sai as long as you have not exceeded 90 days in the last six months using this provision.

If you are asking about arriving with a tourist visa with a stay of 60 days and you will need another 15 days you have the choice of exit country and re-enter for a 30 day stamp or using the 1,900 baht extension of stay from immigration.

yes, it is the bottom portion i am concerned about:If you are asking about arriving with a tourist visa with a stay of 60 days and you will need another 15 days you have the choice of exit country and re-enter for a 30 day stamp ...

however, according to http://www.thaivisa.com/visa/the-new-visa-run-rules.html, the tourist visa is only single entry. i do not know what conclusion to make of these

You seem to be trying to make applesauce out of apples and oranges.

A tourist visa allows you a 60 day entry and you can extend that entry (no leaving country) at immigration for 30 days. You do not exit Mai Sai and return to get those 30 days - you apply at an immigration office without leaving Thailand.

If you want to exit the country you just use as much of the 60 day entry as you want and then exit, enter other country and return to receive a 30 day visa exempt entry. You tourist visa is dead when you exit Thailand - you return on a "visa exempt" entry stamp for 30 days.

Your last point made it very clear but you did not have to make the applesauce comment for i really did not know.

60 day visa obtained abroad then adding a 30-day extension is the easiest, best way IMO.

Paying 1900 baht for a 30-day extension is cheaper, easier and less time-consuming than exiting and re-entering, unless you do want to take a trip.

The comment was meant to be taken as a light humor rather than as a negative - you were confused is all the meaning was. Sorry you took it as something else; but perhaps next time someone will not do so after reading this.

And I was thinking, from when to when you are able to apply an extension. like from day 1 u r in thailand, day 60

The extension will be from the end of your 60 day permitted to stay and is normally issued within the last week of your permitted stay but if you have reason to apply early expect it will be accepted by most officials.

Nice.

If I extend for 30 days, this 30 days is from the end of the whole visa or from the day i extend. so, say, if i extend on the 41st day, i will get 90 days in total or41+30=71 days

From the end of your current permitted to stay until stamp - you lose nothing by doing the extension early.

Clear answer again.

Then to confirm, we can get the extension in Maesai immigration office right. how about other immigration offices like in chiangmai or chiangrai

Any normal immigration office should be able to provide extensions - but border posts are sometimes not a full office and that (main office) may be located in a different area (more in-town). Chiang places should be fine.

All these said is true. I entered Tachilek and reenter.

Now pops up another topic.

Now that I have been in Thailand for 60 days with my Tourist Visa and may still be in Thailand for another 20 days with Visa on Entry, the next time I enter Thailand in around Febuary 2008, will I get the remaining 10 days or will I get 30 Days If I have Visa on entry only.

You will get a visa exempt 30 day entry stamp.
