A spouse and unmarried children under twenty-one qualify as derivatives and obtain conditional permanent residence alongside the investor. Age is not simply the age on the day residence is granted, because statutory child status protection can preserve eligibility, and the calculation depends on the actual filing and pending dates.
Derivative residence is real residence, and it is conditional too
This is the practical difference between EB-5 and every temporary category on this site. Gurpreet's wife would not need a work permit or an employer, because she would hold permanent residence in her own right, conditionally for the first two years. His children would attend school, work if they chose to, and pay resident tuition rates where a state allows it.
What they would also share is the condition. If the enterprise fails the requirements at the removal-of-conditions stage, the consequences reach everyone admitted through the petition. Two details deserve early attention in a family with an older teenager.
Child status protection can hold an age in place during processing delays, but it has to be calculated on the real dates rather than assumed. And permanent residence is not citizenship; naturalization is a separate process with its own residence and physical presence requirements that begins only after the conditions are removed.
