, you need to check with the thai consulate that you're applying at to see if you can get the visa or not.
As a rule you can get it only at a thai consulate in the country where your passport is from. In the US it requires a bank statement showing 7000 dollars in your account (to support yourself while you are here 6 months).
Check the website of the consulate you're applying at and see what they require..
