how long it will take an i-130 visa to be approved?

Answer 1

It is completely unpredictable. It depends on which State you are applying from, as well as immigration office workload. Each situation is handled differently. All applicants have unique criteria that must be evaluated and considered.

When dealing with immigration issues it would be better for you to seek help of a lawyer. He would be able to provide you with more competent assistance tailored to fit your situation.
