Just i'm in confused state to apply or not. If i apply what supporting document i need to show them that after my master's i will depart from united states.

This is the email i got from embassy

We regret to inform you that you have been found ineligible for a nonimmigrant visa under Section 214(b) of the Immigration and Nationality Act. Under U.S. immigration law, all applicants for nonimmigrant visas are presumed to be intending immigrants. In order to be approved for a visa, applicants must satisfy the interviewing officer that they are entitled to the type of visa for which they are applying and that they will depart the United States at the end of their authorized temporary stay. This means that before a visa can be issued, applicants must demonstrate strong social, economic and/or familial ties outside the United States.

Unfortunately, because you either did not demonstrate strong ties outside the United States or were not able to demonstrate that your intended activities in the U.S. would be consistent with the visa status, you are ineligible for a nonimmigrant visa.

This decision cannot be appealed. However, you may reapply. If you have additional evidence to demonstrate compelling reasons to depart the United States that you did not present, you may wish to bring that with you. Otherwise, you should consider reapplying after there has been a significant change in your current situation.

 
If you do decide to reapply, you must submit a new application form and photo and pay the visa application fee again. There can be no guarantee that you will receive a different decision. Only a new interview can determine that.

Thanks
