I just had an update from a friend who was preparing to transfer her visa to her husband as per previous instruction form the immigration office. However, long before she finish the process, they were advised that the law has changed again and she does not have to transfer the visa anymore.

As for my case now, we are trying to get the visa for our new born baby. we have different sponsors. Additional requirements now are:

salary certificate for both parents
bank statement of the father ( at least 3 months)

standard requirements:
passport of baby
birth certificate of baby ( if born in doha)
passport size photo of baby
copy of attested marriage certificate ( attested by embassy)
copy of parents PP and RP ( bring the original of all the documents just in case they want to verify)

Tomorrow will be our 3rd time to try applying for the visa, and everytime they are asking for additional requirement. Hopefully they will process it.
