What if the American immigrant visa hasn't come down yet?

First of all, Gaisu, I'll tell you on the spot if you refuse to sign.

Secondly, there may be a problem of visa refusal. If there is something wrong with your materials, if not, you should not refuse the visa.

Again, it's hard to say when this will be notified. It mainly depends on several aspects, such as whether there are visa restrictions on the policy change of 1 and whether there are enough people in the audit process.

You'd better wait, but you can ask about the specific visa situation. The embassy is obliged to answer relevant questions and will not refuse the visa.

I hope it helps you.
