Check the actual process and applicant records. A shared address does not establish that every person’s information was updated.
Maintain the individual applicant list
Record the notices and steps for each eligible family member. Administrative convenience does not replace their individual eligibility and processing requirements.
Immigration law's derivative rules for the connected employment-based category allow the principal's spouse to immigrate with the principal on the principal's eligibility, without qualifying independently; the same rules cover unmarried children under twenty-one. Whether the program charges separately for family members and how it handles children who are close to the cutoff are matters the official FAQ addresses and which should be read on the day of application rather than assumed from a summary. Create a separate identity and eligibility worksheet for the principal, spouse, and every unmarried child under 21, including passport history, birth information, prior immigration events, and current citizenship. Record each proposed joining person’s identity, relationship, date of birth, marital status, current location, passport, and possible visa-availability issue.
