Well it wont change anything for now....you can file I-130 petition for alien relative and wait until the priority date becomes current and file for I-485 for the adjustment of status but remember the person must continue to maintain her status until the filing of I-485. According to the immigration and nationality act a permanent resident cannot file for the adjustment of status for his her alien relative who is out of status. Currently the wait time for F2A category is about 8 months for Nepalese petition so its totally worth it. gud luck
