Dear Sir/Madam: The National Visa Center (NVC) received your inquiry regarding the immigrant visa petition: HCM2010698107 filed by XXX on behalf of XXX. Due to the numerical limitations on immigrant visa issuance prescribed by law, this petition is not eligible for further processing at this time. The NVC will keep this petition until an immigrant visa becomes available. The petitioner, principal applicant, or attorney of record will be notified when this petition is eligible for further processing. The principal applicant should not make any firm plans such as disposing of property, giving up jobs, or making travel arrangements at this time. For additional information, review the explanation of numerical limitations on immigrant visa issuance below. EXPLANATION OF NUMERICAL LIMITATIONS ON IMMIGRANT VISA ISSUANCE: Immigrant visa processing is governed by the Immigration and Nationality Act (INA) of 1952, as amended, which controls priority dates and the number of immigrant visas that can be issued under certain preference categories. To establish which petitions are eligible for visas, the Department of State issues a monthly publication called the Visa Bulletin. The Visa Bulletin provides a list of cut-off dates that are used to ensure the number of immigrant visas issued each year does not exceed the legal limit established in the INA. Cut-off dates are categorized by foreign state of chargeability and preference category. Only a petition with a priority date that is earlier than the cut-off date is eligible for a visa and consular processing. Please note this petition's priority date, foreign state of chargeability, and preference category can be found at the end of this correspondence. The NVC may begin processing this petition prior to a visa number becoming available per the current edition of the Visa Bulletin. This allows ample time for the petitioner and applicant(s) to obtain and submit all required fees, forms, and documents. This petition, however, will not be eligible for an immigrant visa interview until its priority date is earlier than the cut-off date established in the current edition of the Visa Bulletin To determine the cut-off date and which priority dates are current and ready for consular processing please review the current edition of the Visa Bulletin by visiting the following website: http://www.travel.state.gov/content/visas/english/law-and-policy/bulletin.html To be placed on an email subscription list to receive the monthly Visa Bulletin please send an email to firstname.lastname@example.org , with the following statement: Subscribe Visa-Bulletin First name/Last name (example: Subscribe Visa-Bulletin John Doe) You may also call our pre-recorded cut-off date announcement at (202) 485-7699.
