Dear,

Why dont you let your boy friend arrange the things for you if he really wants to marry you here. The process would be long and lots of documentations needed.

I have a friend who got married here (no child) lots of documentation needed and takes long time to get their marriage certificate issued and therefore she had to fly back to her home country waiting for the attestation of the marriage certificate.

Once it is done, then waiting for family visa to be processed. So get yourself ready for all the process. Good luck for your wedding.
