Thanks. One more question

Thanks for your reply! Sounds like she has not aged-out. The law firm hired by my company does not seem to know how to handle this kind of complex case. That's why no I-824 was filed.

I just googled about I-824, it seems that in order for a child to be eligible for "follow-to-join", s/he must be from a marriage that existed at the time of my admission to the U.S.  My daughter is from my previous marriage that ended 18 years ago. Is she still considered eligible for "follow-to-join"?

Thanks again!
