I want to immigrate to US with my family, by means of student visa for an MBA program or something close.

There are 50 states and thousands of universities.

Correspondingly, there are thousands of immigration services and websites that claim to offer the best advice for a good price.

What should I do? Where to start?

And I'm totally not comfortable to share even this much privet info publicly.

But I've been struggeling to find a way in vain for some time now.
