I'll explain my situation:

My mom is American and my dad is Thai, I have a younger sister as well.

Today my mom and dad went to the immigration to have her non-imm visa renewed and now, it seems as though there's a new rule that everyone has to show pictures of their families at their houses and stuff like that. We also need a copies of birth certificates, old passports, house registration, etc... even though they have copies of this and a backlog of information for 15 years and several inches of documents like visa renewals and passports and such.

Why are they doing this? Is it legitimate? Has anyone else had to do this? And <deleted>?

Where? There is a decentralization process ongoing from reports so that may be part of the reason (local authorities making sure all information is valid and current) as they will be held responsible.

We live in bangkok, we go to the nang linchi embassy and always have.

Is this really necessary? My family doesn't even take photos as a group. I can't remember the last time we did in more than five years.

Photos have always been wanted at first application and sometimes later. Normally it is used to prove living together but with children should not be that important (although normally children would attend the yearly extensions I believe so perhaps they want to see you in photos if not in person.

Immigration for Bangkok is located on Suan Plu and is not an embassy.

Oops, I meant immigration and yeah, it's in the nang linchi area, close to my old school.

The thing is that I'm doing it next Wednesday because taking off school was too inconvenient. Today was just for my mom's visa.

So are you saying that when we go it probably won't be a problem?

Just a formality I suspect. It did appear officer this year was much more careful not to let anything slip (to the point of being sure new photos were used on yearly TM.7).

you should look at getting a Thai PP for yourself to save the hassel for you and your younger sister....

No problem with having dual nationality these days.
