alexam, you say:

"..One solution is to buy business visa for her which can be extended...The authorities are keen on curbing this selling visa business. Ask some Pinoys for more clarification on the matter..."

alexam, the authorities are already tracking your location..  buying visas is illegal, and giving the direct advice to violate the law of State of Qatar will put you in huge trouble... be ready today for the police at your work place...

just checked your profile.. for your age you could be bit wiser.. shame on you!
