Hey guys,
i just got my visa for US immigration (family sponsor based), i know that i should travel to US before the expiry date of my visa. The thing is that i cannot move to the US right away but i need to get my greencard. Can you please clarify the necessary steps for the permanent residence? How long does it take to get it? If i pay USCIS fees before travelling, does it accelerate the process? Should I receive it in person or someone can get it instead of me.
