Their conditional residence is derived from your case, so it is not simply independent of it; equally, a granted conditional status is not cancelled automatically because a child has a birthday or marries. What matters is the outcome of your own record. Each family member is also assessed individually for admissibility.
Keeping the derivative records straight during a project change
List each family member’s grant date and actual notices, then check the I-829 instructions governing inclusion in the principal’s petition or a separate filing. Different dates should not be used to invent an identical deadline or an automatic separate-petition rule. Distinguish relatives who already hold conditional residence from those whose immigrant cases remain pending, and review the project change’s implications for both groups.
Make one page per person and keep it current: full name as it appears on the immigrant documents, the date conditional residence was granted, the notice numbers, the current address, and any pending application. Addresses drift apart when a family moves in stages, and correspondence sent to a superseded address is a common cause of a missed deadline that nobody discovers until later. Confirm as well who is authorised to speak to the project and to counsel about each person’s file, since an adult family member’s information is not automatically shared with the principal.
Review those pages together once a quarter rather than only when something arrives in the post.
