I got 5 years multiple visa
I traveled 2 times once I went and came back
And then after 3 years of tat I travelled again in 2008 I got 6 monthes entry but I stayed more 45 days on that and came back
So now I want to apply for student visa would it be possible for me??

And yes m from pakistan

Your application is likely to be denied... sorry but better look for other countries and always remember.. DO NOT overstay the visa.

If my brothers are born citizen even in tat case too?

Having a brother who is US citizen does not give you any privilege, except the possibility that he may be able to file an immigrant visa for you but it will take about 20-25 years.

M not married still it will take tat much time?

What about if my mom dad does if they get green card?

How old are you?

17 and yes do you have any other way I really want to go there
