An extension of stay based on marriage involves a lot more paperwork and documents than one based on age over 50. What are the benefits of the marriage extension?

I'm a 51 yo US citizen living in Bangkok currently on a 90 day ED visa which expires on July 1st. I have the option of extending for 90 days but I'm thinking changing my visa to Non-ImmO and then extending based on over 50 when necessary.

I live off of income generated in the US, paying my way through life using ATM cash withdrawals. I don't have a Thai bank account, though will soon. The MFA website says 800,000 in the bank "or an income certificate showing an amount of not less than 800,000 Baht." What is an income certificate? Do I need a bank statement with a seasoned deposit or can I use an income affidavit notarized by the US embassy?

If you put in the hours you will get the extensions. Immigration will look at your attendance records. Students without the 10-12 hours per week will get short changed on extension length.

Can you get the yearly extension with an income affidavit from the US Embassy?

Thanks everyone. I've advised her to pick up a cheap flight to Vientiane. She can decide if she wants to apply for a 60 day SETV while she's there or come back in 30 days exempt.

She's in Bulgaria at the moment and will be flying in via Moscow.

Im probably over thinking everything. I just don't want her to run into issues, especially at Suvarnabhumi.
