They go through your whole background and all kinds of stuff. If you have been rejected with a travel visa… I don’t know if it would work for NIW. A travel visa is granted to pretty much anyone, you know. Definitely, if you have time and money to spare… why not? I don’t work at USCIS, but they keep all the records. I would speak with other lawyers. You can find several who do it for free. Frankly speaking….0.1 % chance?
