As your suggestion:
My spouse is going to file I-130, I-485 and G-325A. I am going to file I-485,G-325A, I-693, I-131, and I-765.
Could we put all together in one envelope?
But I am confused about the fee I should send in.
What about I-131 and I-765? Should I pay for them, or it is free to send I-131 and I-765 with I-485 (could you give me a link for it)?
Could we put all fee in one money order?
your answer is very helpful,
thank you very much.
