What should I expect during the US tourist visa interview if I have a sponsor but no savings?

No proof of funds will NOT help.

They’ll wNt to know if you are a Nazi or not. If you answer yes they will let you in, but you’ll have lost your soul. So good luck with that, and I would recommend staying the F out of the USA until there is a regime change! It isn’t safe.

You cannot go to America unless you can open a child care shop or a hospice. If you speak Somali it is a plus .

Check your social media.

my friend worked at the US embassy for decades. It's totally up to the Interviewer. They can reject you for anything. But not having money...won't help you at all. Sorry, but that's how it is. If you had money, that means most likely you won't stay in the US illegally. If you have a stable job, own a house or business your chances go up. They want to know that you will not over stay in the US. They want evidence that something will tie you down back in your country, to make you go back. There is also usually a three strike rule. You usually only get a max of 3 interview opportunities. If you are from a developing nation your chances are even slimmer. Because of Trump policies, now is not a good time. Good luck to you.

They’ve already decided the outcome before the interview.

Well you do y say where you’re from and that matters . But why do ask in Thailand visa group? Make an effort to find the right place you might get helpful answers.

Try a US visa advice group. This one's for Thai visas
