My mom filed a petition for me when I was single and she was a green card holder at that time. My mom became a US citizen in 2015 and I am now married with one child who is a US Citizen (We live outside USA). My priority date is May 31, 2008. What do I do? Should I adjust my status now or wait until I get contacted by NVC? By doing so how does this affect my priority date?
When did you get married? If it was before your mom became a US citizen, the petition has been revoked because permanent residents can file a petition for UNMARRIED children only. There is no category for married children of permanent residents. If you got married after your mom became a US citizen, your category would change to an F3 category for married children of US citizens.
The F3 category has a long waiting period for the priority date to be reached (more than 15 years). The way to speed up immigration is through employment-based immigration. You or your husband may pursue employment-based immigration (EB-2 or EB-3, depending on your qualifications and the job offer). Either way, whether it is you or your husband as the principal beneficiary, you will benefit from each other and children (born outside the US) who are below 21 will benefit also as derivative beneficiaries.
