About Family Reunification

Hello Everybody,
I am a PhD student here at BME from Pakistan. I want to bring my family here. Is there any Pakistani who could guide me for family reunification visa process.....

Search the forums, lots of stuff about this kind of thing on here.

You should talk to immigration services.
I believe family reunification is meant for Hungarian citizens to bring over non Hungarian close family members, not really designed for someone in your situation as a student who is not even a HU citizen.
You haven't given allot of details but if your on a student visa I do not think this is for you.
