Situation:
a.) I am a U.S. citizen and will be working in Dubai.
b.) My wife is under 25, a Colombian citizen and living in Colombia with her daughter/my stepchild.
c.) We were married in Trinidad and Tobago, which has no UAE embassy. Neither does Colombia.

How do I sponsor them? I know the general procedure, and we can obtain the father's permission. I am more concerned about how to get the marriage certificate and father's permission to be recognized by UAE authorities when they don't have a consulate or embassy in Colombia and Trinidad and Tobago.

Will I be able to sponsor them? What will be the process to handle the fact that the UAE doesn't have an embassy in Colombia/T&T?

Thanks!
