About ten years ago, I was deported by the US Immigration Service. Can I get a visa now?

In your case, it is difficult to return to America.

Because of your deportation history, it is impossible to reapply for a non-immigrant visa.

The only hope is to marry an American citizen,

Apply for exemption and then enter the United States with an immigrant visa.

But because the last time you were deported was because of a fake marriage,

Then it's basically hard for immigration to believe that your marriage is real.

So even if you get married, the chances of being released by immigration are very, very small.

You should talk to an American immigration lawyer, and don't listen to these domestic agents lying to you.
