@OldUser understood, what category will it be if my dad as a US citizen will file for them - will that be F4? As a sibling if I file for my brothers will that also be F4? But processing time is different?
Yeah I am looking at the work visa route as well, my older brother is actually a lead software engineer - I am not sure if that will give him more chance in finding a future employer and my other brother's career have been more of the standard administrative work. Do you so happen to have any resources that can help us looking into work visas?
