I want to bring my minor sibling along with my parents.

Sponsoring your parents puts them in the immediate relative category which does not have dependents. Therefore, they would have to immigrate before one or both begins the sponsorship for their son. They would have to show their income to apply for him, but could also use the income of a household member or joint sponsor. Assuming that your parents immigrate, and during the time of their filing for their son, there is open visa availability before your brother turns 21, the waiting time would be approximately 1-2 years. If the visa category (F-2A) date is not available for your brother until after the age of 21 (even counting the adjustment on age afforded by the Child Status Protection Act (CSPA)), his case would fall into the F-2B category for adult children of permanent residents, which currently has a 5 ½ year backlog.Due to the limitations of the Lawyers.com Forums, Alan Lee, Esq.'s (the "Firm") participation in responding to questions posted herein does not constitute legal advice, nor legal representation of the person or entity posting a question.
