I had a similar situation with me and my mom. I am also half Thai with a Thai mother and non thai father. My moms ID and passport expired around 1972 and they deleted her from the system. We had to get her a one year emergency temp. passport and when we went to Thailand she was able to get her ID card and while I was there They asked if I wanted to try to get my ID. I waited a year later which was last year. I brought my USA born abroad certificate and my thai birth certificate . Also I needed my moms divorce certificate translated. pictures of me and a family member then I had to get the head village guy to come to the  amphoe office. After about 3 interviews I was able to finally get my Thai ID. The Thai passport is very easy to get. All you need is your Thai ID card and thats pretty much it . I got my passport this year.

Yep. Agree with 'nickcar'. Very glad for you but different story. You never went through the process as we did as you had your rights by birth.

 I had to get my parents divorce papers and have them professionally translated to Thai. Had to prove my mom had custody of me and my brother.  . My mom had a very old copy of the 40 year old house registration That our names were on and my  over 40 year old american passport helped out. I never had a Thai ID or passport when i was there as a baby. Had a american birth certificate, A thai one and a born abroad certificate.  Then come to find out My mom and dad are actually still married in Thailand but not in the USA lol....but like you said still not as hard for someone that had no birth right there. I have seen how you apply it looks pretty hard. I was pretty nervous when I went in. They said they never had anyone like me doing this. I wasnt sure if i was even going to get it.

Well done, but i suggest that you were not getting your thai citizenship as you had it since birth from your mother, just getting your Thai id card. 

I was automatic american citizen when I turned 18 I had the option but didnt do anything about it. I remember getting some letter about it but ignored it. young and stupid lol.. I didnt have Dual until I went last year to apply

Hello everyone I also applied for Thai citizenship Last year at the District I was born in. My dad was in the airforce and stationed in Ubon over 40 years ago. We came to the United states when I was a few months old and never returned to Thailand Until 2014 with my mom. Met up with my grandma and family... WOW I love  Thailand!!. Not sure why we have never been back. I have returned 3 times in 2 years. Heading back next month. Anyways back to applying for Thai citizenship. I brought my Thai birth certificate and put my name on my grandmas house registration. Did the interview at the local amphoe office. Did a long interview had to get pictures of me and my grandma together at the nearest kodak shop and was told to come back the next day. Did another long interview and had to go back to the village to find the Head village guy to tell him to go the the office for interview. Went back third day and they said I was going to have to come back for a big interview upstairs in a couple days but for some reason we went ahead and did it right there on the spot. I dont speak much Thai at all I know basic words lol My mom was my translator and the Lady at the office spoke decent English as well. So finally she had me get up to take finger prints and picture taken and 5 minutes later I had a Thai ID! I was very excited. When I came back to the states I applied for my Thai passport and just received it in the mail a couple months ago. Cant wait to use it to go through the smaller line at the airport when I arrive through immigration lol...sorry about my boring story just thought I would share.
