Can my spouse and children get green cards through my EB-1 petition?

EB-1 includes derivative benefits for immediate family. Your spouse and each unmarried child under 21 can apply for the green card based on your approved petition, classified as E-14 (spouse) and E-15 (child).

They either adjust status if already in the US or go through consular processing abroad, generally alongside or after the principal applicant. A child who turns 21 or marries during the process can lose derivative eligibility, although Child Status Protection Act provisions may help in some cases. Planning timing carefully matters so children do not age out before the case is completed.
