1) Can I filled “None” in all the A# fields as recommended in the I-485 instructions? Some people suggested to fill “N/A”. The most common advice is that the response “none” or “N/A” is preferred to a blank space.
2) My I-140 has been approved in 2006. However, I have not found my A# on I-797 Approval Notice. However, my co-worker has an A# on his I-797C Approval Notice. My attorney only gave me I-797 page while my co-worker’s attorney only gave him I-797C page. My question is whether the A# is only given on I-797C ? My co-worker's I-140 was approved this year. Is this case that the A# is given on I-797 only after 01/01/2007?
