H-1B Visa Processing and Advising

Pre-Arrival Information

H-1B Immigration Status Information


  • Passport
  • Form I-94: A Form I-94 is one of two immigration documents which, in general, permit a foreign national H-1B status to stay temporarily in the United States during the validity of his or her authorized stay (while maintaining lawful H-1B status).  The H-1B foreign national may receive a different Form I-94 depending on how the H-1B alien chooses to enter the U.S.: 
    • If entering by land -- I-94 card -- The Customs and Border Protection (CBP) officer at the United States port of entry will issue an I-94 card to the foreign national, and will indicate on the I-94 card the foreign national's immigration status or classification (J-1, H-1B, etc.).  For H-1B and H-4 foreign nationals the CBP officer should indicate an expiration date on the I-94 card.  The expiration date refers to the length of time an H-1B foreign national has permission to remain temporarily in the United States.
    • If entering by air or by sea -- passport Admission stamp -- this stamp will be given to the H-1B foreign national by the CBP officer at the port of entry when he or she arrives in the U.S.  The individual's passport will be stamped with the date of admission, class of admission (H-1B) and admitted-until date (expiration date).  The foreign national's arrival information, including the Admission number, will be processed electronically by CBP.  We strongly recommend that an electronic Form I-94 be printed out and saved after entrance into the U.S.  You can access and print your electronic Form I-94 by clicking here
  • I-797: This is the CIS document with which an alien applies for an H-1B visa at a United States Consulate or Embassy. To apply for H-1B status while in the United States in some other status, the prospective employer of the alien must submit an H-1B petition to CIS. CIS issues an I-797 upon approval of an H-1B petition submitted by the alien's prospective employer. An H-1B alien can be employed only by the employer designated on the I-797. An I-797 permits an H-1B Temporary Worker to stay temporarily in the United States during the validity of the H-1B alien's authorized stay (while maintaining lawful H-1B status). The I-797 specifies the date to which an H-1B alien has authorization to be employed by the employer listed on the I-797. The CIS dictates that the employer should retain the original top portion of the I-797 form, and give the bottom tear-off portion to the employee. To facilitate visa application and travel and re-entry, however, we will give the original top portion to the employee, with the understanding that it will be returned to the Office of Visa and Immigration Services as soon as he or she returns to the U.S.

Maintaining Legal H-1B Status

H-1B Temporary Workers must comply with the following regulations to maintain lawful H-1B status:

  1. Maintain a valid passport
  2. Complete your stay by the date specified on your Form I-797 (H-1B Approval Notice) or apply for an extension through OVIS as allowed by regulations at least 90 days prior to that date
  3. Accept employment only from the employer for whom USCIS approved an H-1B petition (Dartmouth College) and adhere to the terms and conditions specified in that H-1B petition
  4. Work only at the location listed in the Labor Condition Application (LCA)
  5. Work only during the period of validity listed on the approved H-1B petition and LCA
  6. Notify OVIS and USCIS of any change of address within 10 days by filing Form AR-11 (found here). 

An H-1B employee who does not comply with these and all other USCIS regulations could be considered to be out of status, and may need to leave the United States.

Additional Notes

  • Regulations allow an H-1B employee whose status has expired but for whom an H-1B petition and request for extension was filed prior to the prior H-1B petition end date to continue employment with the same employer for a period not to exceed 240 days beginning on the date of the expiration of the authorized period of stay.  Authorization is rescinded if the petition is denied.
  • An H-1B employee who seeks to change employers must have a new H-1B petition filed with USCIS or some other appropriate employment status approved by USCIS before he/she can begin the new employment.
  • Dependents with H-4 status are not authorized to work in the United States.

Travel and Re-entry to the U.S

Please see separate sheet entitled "Travel and Re-Entry to the U.S. on H-1B or H-4 Visas" for additional information. The following is only a brief summary of travel and re-entry procedures.

  • Valid U. S. H-1B visa
  • Valid I-94
  • The original top portion should be requested from the Office of Visa and Immigration Services for the purpose of travel outside the U.S. or visa application.
  • A copy of the valid I-797 issued by CIS to the alien's employer
  • A current letter confirming that he or she is employed in the same position as described in the H petition and needs to reenter the United States to continue that employment.
  • Original I-612 Waiver Approval Notice form the CIS, if appropriate (former J-1 researchers subject to 212 (e) home residency requirement, who applied for and received a 212(e) waiver)
  • A copy of the complete H-1B petition filed by the Office of Visa and Immigration Services, including letter of employment offer, and certified LCA form.
  • Though not required, it is recommended that an alien also have evidence of adequate finances, and or a letter from the department indicating on-going employment.
