Plan around eligibility, not a brochure word. A spouse and unmarried children under twenty-one may be included, each must be individually admissible, and each proceeds only when a visa number is available. Age protection for a child is fact-specific, so no promoter can promise a particular outcome for a teenager. Each dependent is an applicant, not an addition to yours. A promoter plays no part in a spouse's admissibility or a child's age calculation and cannot be answerable for either. Give every family member their own file and their own set of dates, then have someone who acts for you, rather than for the project, check them.
Building a family plan on eligibility, not slogans
Sit down with the actual dates: each child's birth date, the projected filing, and the visa availability that applies to your chargeability, which commonly follows country of birth. From there decide schooling and moves, knowing that a pending or approved petition confers no work or travel permission. Adjustment of status inside the United States is available only to someone actually eligible for it.
Confirm the milestones that actually move a child's position: the filing date, the priority date, visa availability for the applicable chargeability, and the child's own age at each. Conditional permanent residence, once granted, is conditional for the family as well, and the later petition to remove conditions turns on the investment's record rather than on anything the household did. Plan schooling around what each person's status permits at the time.
