After Favorable recommendation - next step in J-1 Waivers Posted May 23, 2018 · Report reply Hi Power, Congrats! Happy for you. For me USCIS took only a day. It shouldn't take too long. I don't know how H1B works. If you want to try AOS through EB1/2 then I recommend you contact a lawyer. You'll need to file the I-140 petition first, then depending on which one of EB1/EB2 or NIW you want to apply for you'll submit your I-485 application (green card). It's pretty complicated and I strongly recommend you find a lawyer who knows these procedures. Best of luck!
