Because I am from India, I would never get a Green Card through EB-2 (though I have two approved EB-2 petitions). Yesterday, USCIS denied my EB-1 petition using argument which are against the law. Now I have to leave US :(
I have an approved O-1 (extraordinary ability), but apparently, once you have filed for a Green Card Adjustment of Status, you can't get a visa stamp for anything other than H-1. Not sure if I can come back!
