My fathers I-130 just got approved (it took about 3 months). Hes now in US, so he will go through AOS next step. Im now preparing I-485 and other documents for him, I got some questions:
1. What is the A# on Part 1 of I-485?
2. I saw in the Information Source thread, it mentioned that "Visa number is the one in red", I wonder where do I need to use the Visa Number?
3. On Form 325A, Applicants residence last fives, does it count the residence outise of US?

I appreciate your replies.

Thanks

1. A# should be on the receipt notice for the I-130, or written on the back of the I-94.

2. On the I-485 they ask you for Immigrant visa number.

3. Good question. I dont believe so, because they also ask the "last place you lived outside of the USA", but I would guess it cant hurt to put places outside of the USA. Do the instructions not say?

3) you have to list all residences regardless of location.

Thanks for you guys response.

But one more question:
on 325, theres a box for applicants signature, which is my fathers signature, should he sign in English or Chinese?

Below that theres a line saying "If your name alphabet is in other than Roman letters, write your name in your native alphabet below:" does this mean I need to type his name in Chinese character?

Thanks a lot.
