Lately I've been thinking about just going back home. I know if I do go back home I would be ban for 10years, so my question is would they deny me the next time I reapply for a visa? Also, im thinking of applying for a Canadian visa would that affect of my chances getting that Canadian visa?
Yea, they will deny you the visa if you apply while the 10-year ban is still in effect.
About the Canadian visa, I would think it would depends on which one you apply for. If you're getting a temporary visa (student, visitor etc...), they might view the presence in U.S. as a negative factor.
If you have a sponsor from an employer, then I think it wouldn't matter.
I don't know why people keep bringing up Canada, it's not easy getting a permanent visa unless you have a family there already or have employer sponsoring you (which is hard given most of us can't work, so we don't have experience).
