hi, I think USCIS is pending your case, but they are seldom to hold it for a long time. besides the tax document, is there any problem too? If u can find ur case no. in USCIS website, that means they are still have your application, u NO NEED to apply it again, there is no use.
for my opinions ....
1. write a letter to USCIS first. if they didn't reply it, u can write a letter to some media (e.g. NBC, CBS ...etc), they would like to help.
if still cannot .... 2. u need to get a lawyer to help.
hope u can get it done soon. takecare.
