Assuming you are working here? You have to have a sponsor in Qatar to have an RP... which means your sponsor should be taking steps to renew your RP... Even as a canadian citizen I don't think you can enter on a regular visit visa if you have had an RP issued before....

As far as I am aware, even if your wifes RP expires only next year - because your RP will expire, hers will too - I stand open to correction - but your wife is here because of your sponsorship - if yours expires for any reason, she wouldn't be allowed to stay either...

Help anyone else?
