Adey..

We get our passports at a very young age so we definitely need the father's signature :) for renewal I don't remember having any man's signature or approval. We just fill out the needed forms ourselves.

It is legal for a woman above 25 to travel without a man's permission (at least so I've heard.. never tried it myself).. however in every Qatari household you'll find different views and practices. In my family I can get on board a plane all by myself provided that I don't stay abroad without relatives..they could be cousins (females) ..they could be in-laws etc.

In my husband's family it's more strict..

I know other families who pemit their daughters (even below 25) to study abraod without a chaperone.

Again.. no one-fits-all rule..
