What is a U visa ( U visa Interim Relief)and how long does it take for approval?? If a person applies for her and her kids, and one of her children is under 21 but married. Can the married child be accepted to hold a U visa? San Francisco.CA

Here's a good overview of the U Visa:
http://www.ilrc.org/resources/U%20Visa/Frequently%20Asked%20Questions.html

Note that the first thing it says is that none have actually been issued yet.

I only scanned it briefly and did not find your issue addressed specifically... so read it carefully (at least the sections that might apply) - and check the links it refers to also.

Hope this at least helps to get you started.
