Here is my situation:
I am currently holding an H1B visa.
I have applied for I-485 before and the case was denied.
I currently have a new I-140 that was approved but no I-485 was filed yet on the case.
The problem is I need to cross border to Canada and come back to US.
I wonder if I would have any difficulty coming back to US?
Nervous, please help.
Thanks!
