Applied for Extended Stay for my Mother (I-539) in August, 2011 and waiting for response, mean while I would like to apply 485 for my Mom. Currently I am having GC and will be eligible for Citizenship by end of next year. I am trying to keep her on legal status all the time and no or less issues with immigration.
Here are my question:
1. Can I apply GC for my Mom?
2. Do I need apply labor first then I-140 then I-485?
3. Once I become US Citizen, can I update this file with my latest status? Or I need to put new application?
Any kind of help is appreciated.
Thanks in advance for any suggestion.
