Hello

I want to study in newyork usa and I have done BBA(H) which is three year program. I came to know from someone that three year degree is not recognized in U.S.

So I have to do some additional courses to make it a four year degree. Just want to ask that where I can get information about it, any website about american education board anyone know or anyone can helpme telling me some facts about it. I will appreciate anyone's good advice.

Once you pick your school, you'll want to find out how to get credits for what you already know.

You'll pay a fee (far less than tuition) to "test out" of the classes that cover what you already know. If you pass the test, then you get the credits.

The advisor at the school will be able to direct you more specifically about the best way to go about it once they see your degree and where you got it.

As mentioned, there is no "National Board" that accepts or not accepts specific classes you have taken, But depending on what schools you have atteneded and what classes you have taken, these classes can be transferred. If your degree is equal to a degree in the US then it may be accepted for further study in a advanced degree in the US.

It is not the number of years bu the number of class credit that you have.
It is humanly possible to do a US degree in three years, but others may take 5 years to complete. Callingit a 4 year degree is really a old term and not really valid.

You would need to contact one or more schools in the US, and they will review your transcript of classes and see what level you have. Many of the major colleges have foreign student departments that help with Englich and culture to help a student adjust to study in the US.
