What Is the Process to Obtain a Non-Immigrant Multiple Entry Visa Based on Marriage to a Thai National in Vietnam?

Today I have received my non-immigrant multiple entry visa based on marriage to Thai. Me and the wife arrived Wed, February 5 at Ho Chi Minh City, Vietnam, checked in at an Airbnb and spent the night. Thursday morning, around 08:45 we arrived at the '[Royal Thai Consulate-General in Ho Chi Minh City]([members only])'. Only a few people were in line before us.

The service was kind. We brought with us:

* Passport with at least 6 months validity remaining

* Completed application form (I filled it in advance using the GIMP graphics software)

* Recent photo, 4×6 cm in size with a white background

* Original and copy of Marriage Certificate (two pages)

* Copy of the Info page and previous Thai visa page of my passport

* Visa fee 200 USD

* My Thai bank book with around 140k THB balance

* My wife's ID and a copy of it

* My wife's house registration card and a copy of it

* Documents for visa extension (คร.2) that we received along with the marriage certificate (don't know much about these, yet)

* Itinerary of an outgoing flight I happen to have at the end of the month.

I can't be sure which documents the clerk examined and which they did not.

My wife was asked to provide a letter that if I remember correctly is a request from her to provide me with a visa. She was given a blank page and a pen and she wrote it on the spot.

We spent another night and earlier today we arrived around 13:45 at the same consulate, to the sight of a group of people ahead of us very similar to the day before standing in line. We were let it when our turn came after quick forehead temperature tests.

Inside we received my passport with a one year valid non-immigrant multiple entry visa based on marriage to my wife.

I chose Ho Chi Minh City for this following advice in this post:

[[members only]/)

...where it was made clear that that consulate does not require a proof of funds (400 THB in a Thai bank account by my name for at least two months consecutively).

Having this visa means that I should be able to do border runs every 90 days, if I don't happen to travel anyway. And if I succeed in accumulating the above mentioned proof of funds then I should be able to get a stamp for 1 year of consecutive stay, in which my only immigration related chore would be 90-day reports.

Thank you so much, James, Benjamin and Robert. May I buy you beers?
