my friends is a couple, the husband is a principal asylee with ND 04, because of some of personal reasons, the husband applied I-730 for his wife in 2005 and have not got any result from USCIS. for USCIS speed up approving I-485 for asylum, if the husband get approval before USCIS adjudicate I-730 of his wife, it is possible that USCIS reject the I-730 because the husband has been a permanent resident not a principal asylee.
