National Visa Center
The National Visa Center (NVC) is a center that is part of the U.S. Department of State that plays the role of holding United States immigrant visa petitions (as well as Form I-129F petitions for K-1/K-3 visas) approved by the United States Citizenship and Immigration Services until an immigrant visa number becomes available for the petition, at which point it arranges for the visa applicant(s) (the petition beneficiaries) to take the visa interview at a consulate abroad. It is located in Portsmouth, New Hampshire. It was established on July 26, 1994 on the site of an  Air Force base that was closed down by The Pentagon. In most cases, the person or entity that files the original USCIS petition (also known as the petitioner) differs from the person (or persons) on whose behalf the petition is filed (also known as the beneficiary or beneficiaries). The beneficiaries are the persons who may subsequently apply for a visa based on the approved petition, and NVC's communication is with the beneficiary (with the petitioner getting a notification at the beginning). In this article, the terms "beneficiary" and "visa applicant" are both used based on context. Petitions that go  through the NVC. Form I-130 petitions. Form I-130, Petition for Alien Relative, is used by United States citizens and permanent residents to petition for immigrant status for their immediate relatives. The IR subcategory in the Form I-130 category is uncapped, and therefore the NVC immediately begins processing the application. However, the F subcategory has numerical limits, and is generally backlogged, and therefore applications in this category may have to wait. Note that wait times depend both on the type of visa in the F category, and the country of chargeability. Form I-140 petitions. Form I-140, Immigrant Petition for Alien Worker , is used by United States businesses (and in some cases, by the immigrant beneficiary himself or herself) to petition for immigrant worker status for the beneficiary in one of the categories EB-1, EB-2, and EB-3. All the categories are numerically capped. For any given country of chargeability, EB-1 gets higher priority (and therefore has lesser backlog and a shorter wait time) than EB-2, which in turn has higher priority than EB-3. For some combinations of country of chargeability and category, the priority date may be current, in which case NVC begins processing immediately, whereas for others, applications in the category  may have to wait. Other immigrant visa petitions that go through NVC. The following immigrant status petitions also get sent to NVC: Form I-129F petitions. Form I-129F is a non-immigrant visa petition intended for the fiance(e) and children of the fiance(e) of a United States citizen, with the intention of marriage with the fiance(e). The corresponding visa category is the K visa. If the petitioner and beneficiary fiance(e) marry within three months, the fiance(e) can undergo Adjustment of Status. This is a rare case of a non-immigrant visa category with explicit immigrant intent. There are no cutoff dates  for these petitions. Provisional Unlawful Presence Waiver. A Provisional Unlawful Presence Waiver is a waiver provided by the USCIS indicating that it waives unlawful presence in the United States as a ground of inadmissibility for a given applicant. It is obtained by applying with Form I-601A to the USCIS. It is used by people currently unlawfully present in the United States prior to departing the United States for a consular interview. USCIS notifies NVC once the Form I-601A is approved and the Provisional Unlawful Presence Waiver is granted, so that NVC can process any visa application for the applicant based  on a petition listing him or her as a beneficiary. Petitions and visa categories that do not go through the NVC. Form I-129 petitions for non-immigrant workers do not go through the NVC. For these petitions, once the petition is approved by the USCIS, the beneficiary may directly apply for a visa at a United States consulate or embassy abroad. Some of the Form I-129 categories have numerical limits, but these limits are taken care of by the USCIS at the time it receives the application. Moreover, due to a limit of six months for receiving the petition (i.e. , the petition can be received at most six months before the proposed start date) there cannot be huge backlogs; in case more petitions are received than the numerical limits the additional petitions are rejected and the petition must be filed next year. Among immigrant visa categories, the Diversity Immigrant Visa does not go through the NVC. The program is managed by the Kentucky Consular Center of the U.S. Department of State. Distinction between immigrant visa applications outside the United States and Adjustment of Status applications. There are two ways to become a United States Lawful Permanent Resident. The key  difference between the two methods is that for (1), the key decision to approve the beneficiary's transition is made by a consular officer employed by the U.S. Department of State and stationed in another country, whereas for (2), the final decision is made by a USCIS Field Officer. The National Visa Center is involved only for method (1). In case method (2) is being used, the NVC will not receive the petition at all if the Adjustment of Status application (Form I-485) is filed concurrently with the petition. If, however, the petition is filed as a standalone petition, the  NVC may contact the beneficiary, and the beneficiary must indicate to the NVC in response that he or she is adjusting status and does not intend to apply for a visa. In this case, the NVC holds on to the petition until it is requested by a USCIS Field Office. If the applicant does not respond, the NVC continues processing it for a visa application. However, the numerical limits apply to all petitions regardless of whether method (1) or method (2) is used, and are managed by the Visa Reporting and Control Division of the Department of State. For Form  I-130 and I-360, in some cases, another option called Direct Consular Filing (that bypasses the NVC) is available; however, this applies only to categories with no numerical limits. Steps. The petition is received by the USCIS. When the USCIS receives a petition, it puts it in a processing queue handled by USCIS and marks the date of receipt of the petition. If approved, and in the case that the category is numerically capped, the petition's Priority Date will be set to this date of receipt. Note that for I-140 petitions that require labor certification, the Priority Date is set  as the date that the application for labor certification is received. The USCIS may take some time to approve the petition. The USCIS publishes both its processing time goals and its current processing times, which are approximately 7 months. For some petitions, the USCIS may issue a Request For Evidence or Notice of Intent to Deny. The USCIS may deny the petition and the denial may be appealed. For Form I-140 petitions, it is also possible to speed up the process by availing of the Premium Processing Service. Throughout the process, the NVC is not involved. It is only if  and after the USCIS approves the petition that the petition is forwarded to the NVC in Portsmouth, New Hampshire. As soon as it receives the petition from the USCIS, NVC gives the petition a case number through which the status of the petition may be tracked and contacts the applicant confirming that the petition was received. Note that this case number differs from the USCIS case number and also from the immigrant visa number (that, for capped categories, may not be immediately available). For numerically limited visas, the National Visa Center may hold the petition until a visa number becomes  available. For visas in numerically limited categories, the date that the petition is received by the USCIS is treated as the Priority Date for the application, with the exception of petitions that require labor certification. For petitions requiring labor certification (as is the case for some Form I-140 petitions) the Priority Date is the date the application for labor certification was received by the U.S. Department of Labor. Applications are processed from earlier to later Priority Dates. At any given point in time, the cutoff date (also known as the Qualifying Date) for current processing for each combination of category  and country of chargeability is available, and published in the Visa Bulletin. If the Priority Date is earlier than the cutoff date for that category at the time NVC receives the petition, it immediately starts processing the application. However, if the Priority Date is later than the cutoff date, NVC holds the application until the cutoff date is about to approach the Priority Date. At this point, NVC contacts the beneficiary and starts the processing. An application whose Priority Date is earlier than the cutoff date is termed "current". NVC is "not" responsible for managing the queue of applications or  updating the cutoff dates. That responsibility lies with the Visa Reporting and Control Division of the U.S. Department of State, that also publishes the Visa Bulletin and issues immigrant visa numbers. Moreover, the applications that go through the NVC are not the only ones in the queue; the queue also includes Adjustment of Status applications. Some implications of the way Priority Dates work: NVC processes the application, arranging for a consular interview. NVC does the following to move forward on the beneficiary's visa application: NVC's first communication with the visa applicant, even before collecting fees, asks the applicant  to choose an agent to represent him or her in communication with the NVC. The applicant may do so online through Form DS-261, Choice of Address and Agent. There is also an outdated equivalent form called Form DS-3032, that is filed by paper. The NVC hands things off to the consulate or embassy interviewing the applicant. After the NVC schedules the interview and forwards the materials to the consulate, the responsibility for further processing belongs to the consulate. If the consular officer adjudicating the beneficiary's visa application believes the underlying USCIS petition was approved in error or is no  longer approvable the officer may return the petition to USCIS for revocation/reconsideration. This communication occurs directly between the consulate and the USCIS. NVC is no longer involved. Termination of registration. The registration of an immigrant visa petitions is terminated if the beneficiary fails to apply for an immigrant visa within a year of notice of immigrant visa availability. However, the petition may be reinstated if, within two years of notice of visa availability, the alien establishes that the failure to apply was for reasons beyond the alien’s control.
