Assuming you are asking about the B1/B2 is a visitor's visa, please keep in mind that this does not allow you to work in the U.S., but if you have a foreign employer, you may be able to come to assist with managerial tasks such as setting up an office, negotiating contracts, or attending business meetings on behalf of the employer. If you have no employer, and are just coming on your own for business purposes, you must be sure to emphasize that you are not receiving remuneration paid on U.S. soil. They are very picky about that. Education is not a prerequisite, but if you are attending school in the foreign country, then it helps demonstrate your "ties" to the foreign country.
Remember, this is a non-immigrant visa, so you have the burden to prove you don't intend to immigrate. Best of luck!
