A spouse and unmarried children under twenty-one may be included as derivatives, each receiving conditional permanent residence alongside the investor. A child who reaches twenty-one during the process can lose eligibility, although provisions exist that may protect a child’s age in defined circumstances, and those provisions have to be checked against the particular timeline.
The age question is the one that needs a calendar first
This route differs from the temporary categories in an important way: the family members are not dependants living on someone else’s permission but permanent residents in their own right, able to work and study without further authorization. That makes it attractive to households where a spouse has a career and a child is approaching university. The corresponding risk is the age limit.
Because the process can take years, a child who is nineteen at the outset may be over twenty-one by the time an immigrant visa becomes available, and the rules that can preserve a child’s age for this purpose depend on how long the petition itself was pending and on how promptly the family then acts. A household with a child in the late teens should have that timeline mapped by someone who does this work before deciding anything else, because it can determine whether the whole plan is worth starting now or better started immediately.
