I am not sure but I think that they can count the same 40 quarters on each of their I-864Ws.3x40=120 quarters works for them? My brother met his wife when they studied in the US university, they got married before he started work, and their son is under 18.
This is sibling immigration, do I need file I-864 for them?
No, he does not need to be working. It's 40 quarters accrued over his lifetime.Thank you for your reply!
My brother is worried he has not worked in USA for 2 years, so he asked me to file I-864. Is 40 quarters of work enough or also requires he is working in USA?
