I am a U.S. lawful permanent resident, who has filed an I-130 visa petition for my 23-year-old son in the Philippines. He has a priority date in category 2B, and we have been carefully watching the movement of dates on the Visa Bulletin, but he still seems to have many more years to wait. Now I have been thinking about submitting an N-400 application for U.S. citizenship, which would be especially helpful so that I can petition my parents to come to the U.S., as well. But someone told me that when I become a citizen, my son will automatically move to category F1. I just looked on the Visa Bulletin, and the priority dates in that category are even further away than in 2B! Should I wait to become a citizen? Bringing him here is my first concern.
