A 50-year-old woman comes to the U.S. as a permanent resident in April 2014. Can she file I-130 petition for her under 21 son who will turn 21 in September 2015? If she can and in case the processing time goes past September 2015, will the whole process be delayed because it went past the beneficiaries 21st birthday. The beneficiary (the son) currently lives in the U.S. at an F-1 non-immigrant status. The woman has another son, who is a U.S. citizen, through whom she gained the permanent resident, can also file petition for his sibling at the same time. Which way will be faster? All good pieces of advice will be greatly appreciated.
