questions about Form G-325A, Biographic Information

1. File Number: A (that number should be located on I140 approval, right?)

2. Applicant's last address outside the United States of more than one year

Is that the address before I come to US 6yr ago? I haven't been back to China since I came.

3. At the bottom of the page, in the box outlined by heavy border, Alien Registartion Number, is that same as the A number in my question #1?

Thank you!
