I have a valid F1 visa, , ,,, so if I go to the interview and and then if I have to wait for the FBI clearance , does this mean that I will not be able to go back to US again,?
As far as I know USCIS cannot revoke a visa since they don't issue them. However, USCIS can rid a person of their non-immigrant status just as easily as a consulate can cancel their visa.USCIS do not revoke visas that easily.
obviously, a person out of status CANNOT adjust status unless they are an immediate relative of a USC. They also may be barred from getting an immigrant visa.Unless ofcourse the obvious which is Out of Status
cannot adjust status, same thing as above- illegal entry
most likely generally inadmissible- criminal felony, etc.
USCIS does not issue visa, but they do change of status. In this case person can stay in the US on "change of status" documents, but you might also know, if person goes back, it is not easy to get a visa. It's easier to change the status or extend the visa in US. USCIS of course can cancel visa, but they dont do it on a whim. They have to prove that this person has violated his alien status while in US (on grounds of out of status-unauthorized employment-criminal record-etc) and then they can revoke a visa and issue deportation orders.As far as I know USCIS cannot revoke a visa since they don't issue them.

good luck proving non-immigrant intent when trying to extend or change your status in the US AFTER you have applied for immigration. That's it, folks.In this case person can stay in the US on "change of status" documents, but you might also know, if person goes back, it is not easy to get a visa.
