I have a US address and US bank. My SS benefits are deposited to my US bank. Social Security though has my Thai address. I signed up for SS using the Manila Social Security office. When I changed my address in Thailand I informed the Manila SS office.
That’s up to you. You want to do this through the Manila Social Security office in the Philippines. That is the office that serves Social Security recipients in Asia. Once you are here then email them to make contact and ask for instructions.
I do get the letter and I have never had any problem getting the letter, either in Bangkok or in rural Sisaket province, and I have never had my benefits interrupted. I find mail delivery in Thailand to be pretty good except maybe around New Years. I return the letter using Express Mail service which is faster and is tracked.
I’ve heard the stories too but that has not been my experience. You can test the mail service yourself while you are living here. It doesn’t do any good to have it sent to my sister’s house in Nevada.
I moved to Thailand when I was 60 years old and I am married to a Thai. By the time I was 65 I was sure that I was going to be staying in Thailand permanently. If you already have Part B I think you can still get out. So, like me, be sure you are leaving the US for good or investigate how to discontinue Part B later when you are sure.
I’ve always used a Thai address with Social Security. Last year I moved from Bangkok to Sisaket province. When I got my proof of life letter in Sisaket it said that it was their 2nd attempt. I returned the letter using EMS and never had an interruption in my benefit deposits. I find mail delivery in Thailand to be reliable and reasonably fast for international mail except around New Year’s.
I live in Thailand . I use my sister’s in the US for my bank address. Also keep a standard US phone number for authentication. I use my Thai address for Social Security. I used my Thai address for my Fidelity retirement accounts so California taxes are not withheld when I make withdrawals. I recommend two credit cards, each from a separate bank.
