I do not have a Thai bank account, but my wife does. I send her about 8,000 USD a month. I am currently paid about 14,000 USD a month, will this be enough to apply for a Marriage visa?
There are some options to choose from in order to meet the financial requirements for the Marriage visa. If you do not have a Thai bank account, you may open one under your name and deposit the amount of 400,000 THB. But, if you are earning a monthly income of 14,000 USD, then, this is sufficient in order to apply for a Marriage visa.
You just need to provide evidences for this income which will be presented at your embassy in Thailand to obtain the income affidavit for the application.
