Approved in Saigon / Thanh Pho Ho Chi Minh.
I did not season the account. I transferred the money ~3 days before applying.
I did not use an agency.
I am not a freelancer: I am full time employed for over 2 years at the same job.
I submitted W2 statements, not my full prior 2 years taxes.
I drew a bright red box on the bank statements for my "income" transactions
I submitted my payroll statements for the past 6 months, all 12 of them :(
I work remotely for an international company that operates in Thailand (think Agoda, but not Agoda). There was no concerns from them about me needing to get a Thai work permit instead of DTV.
My employer let me generate a "This kid works remotely for us and earns $XXX/mo"
As an American, any important currency numb ers (like bank account totals or income letters), I converted to Thai Baht, so they would not be confused with SGD / HKD / etc which uses the same currency symbol, but is lower value (which could put you at risk for being below limits if misunderstood).
