American visa materials are fake, that is, the job is fake. How did they find out?

American visas need to be signed in person. Never submit false materials to discover that they are true. However, then the embassy will leave a record of your failure and the reason why you sent it to him later. If you see your own situation, it is even more hopeless.

Visa officers often get to the bottom of some details in the interview process, and these details can't be fabricated by forgers in advance.

If you sign this time, you don't have to sign it in person before the visa expires.

It's really not easy to go to the United States. Both tourists and immigrants should submit real materials to avoid more complicated situations in the future.

No organization or individual can give you 100% approval, because it really depends on the individual situation: the organization or individual will give you a refund, but your records and reasons cannot be erased.
