Here in Saudi ARabia, to apply for family visa there are some criteria. Like His min salary should be 4,000 riyal and he should have original degree certifiate etc etc..
but some people here make fake degree certificate/salary certificate and apply for visa...
their family stay in saudi arabia is haram/halal? as they hv taken family visa by submitting fake certificates?

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

Undoubtedly, forging documents is forbidden and it is not permissible to resort to it; we have already issued Fataawa 92226 and 86193 clarifying that this is forbidden.  

However, if a person could bring his family by this means (to the country where he lives), it cannot be said that the residence of his family with him is forbidden, but he is obliged to repent to Allaah for forging documents.

Allaah Knows best.
