What Does the National Visa Center Do?
After a Department of Homeland Security's Bureau of Citizenship and Immigration Services (BCIS) office in the United States approves the petition, it sends the petition to the National Visa Center (NVC). NVC does the following:
• Assigns a case number
• Sends Form DS-3032 Choice of Address and Agent to the applicant (your relative in Yemen). The applicant selects an agent. The agent can be anyone, including the applicant.
• The NVC will mail all future letters (except for the Affidavit of Support, Form I-864) about processing the immigrant visa case to the agent. Make sure the postal address is correct and is kept up-to-date.
• Sends the bill for the Form I-864 Affidavit of Support processing to the petitioner
• Sends the Form I-864, Affidavit of Support to the petitioner after the petitioner pays the I-864 processing fee
• Sends the bill for immigrant visa (IV) processing fee to the agent after the applicant sends form DS-3032 Choice of Address and Agent, to the NVC
• Sends an instruction package to the agent after the agent pays the immigrant visa application processing fee, form DS-230
• Reviews information for technical correctness and completeness.
• Sends the petition to the embassy or consulate where the applicant will apply for a visa when the case file is complete
Point of clarification - the NVC does not approve anything. The NVC collects the visa application and some of the supporting materials, puts it together with the approved petition, and sends it off to the consulate where the interview is to take place.
The NVC notifies the petitioner and the beneficiary a few months prior to when it is expected that the priority date will become current.
The NVC also sets the interview schedule for most consulates.
The consulates approve or deny the visa application. How long they will take to make that decision can vary greatly from applicant to applicant at certain consulates, including the one in Islamabad. No one can predict how long the required background investigations will take for any particular applicant.”
Certain conditions and activities may make a relative ineligible for a U.S Permanent Residency. Examples of these ineligibilities are:
• Drug trafficking
• Having HIV/AIDS
• Overstaying a previous visa
• Practicing polygamy
• Advocating the overthrow of the government
• Submitting fraudulent documents"
