documents required in naia

hi, i have been checking out a few forum treads regarding husband sponsorship visa and required docs at naia, but to be honest im not really satisfied of the answers/replies and the answers im getting from other people i know. i have recently got my wife's visa and she already printed the visa via moi.gov.qa in the philippines all she needs to do is to send it to the qatar embassy there for authentication. my question is, what are the actual documents that the immigration will ask from her on the day of her flight going here in qatar. i dont want to receive a call from her on that day that she will not board the plane because of this and that. so if somebody could help me on this, somebody who have recently brought his wife under husdand sponsorship i would GREATLY appreciate everybit of information i can get.i know you took a while to finish reading. thanks alot.
