A nonimmigrant visa is the proof of assessment conducted by the officials at the U.S. Embassy or Consulate that certifies a person may seek admission to the U.S. for a specific purpose. Therefore, you will need to submit certain required documents at the U.S. Embassy or Consulate to explain the purpose of your visit to the U.S. Your Certificate of Eligibility document (DS-2019) is necessary to obtain a nonimmigrant (J-1) student visa to attend Northeastern University. Do not enter the United States in Visitor status (B-1, B-2, WT, or WB). If you enter the U.S. on a tourist visa or on Visa Waiver Program you will be required to leave the U.S. in order to re-enter on a proper student visa.

No assurances regarding the issuance of visas can be given in advance. Therefore, it is recommended that final travel plans or the purchase of nonrefundable tickets should not be made until a visa has been issued. After the visa is granted and processed, check your passport to be sure you received a J-1 visa stamp, and that any dependents received J-2 visa stamps. Also, be certain that the original DS-2019 was returned to you, as you must have the original with you when you arrive to the United States. Sometimes, the document is returned to you in a sealed envelope (in this case, do not open the envelope), which must be presented to the immigration inspector when you arrive.
