To check the status of an open U.S. immigration visa case, contact the U.S. Citizenship and Immigration Services. The USCIS oversees lawful immigration in the United States, according to its official website.
The USCIS provides nationwide telephone assistance through the National Customer Service Center. The NCSC can check the status of an open case and provide additional information on immigration services and benefits, states its website. It provides services in both English and Spanish, as well as a separate toll-free number for the hearing impaired.
Live assistance and automated options are both available. As of February 2015, representatives are available Monday through Friday; however, hours of operation vary depending on the location within the United States. Generally, for most U.S. locations, the hours are 8:00 a.m. to 6:00 p.m.
The automated phone system can provide the status of an open case as well as general information about basic eligibility, forms filing and procedural inquiries. It's available 24 hours a day, 7 days a week. Inquiries on case status can also be checked through the USCIS official website. Customers should be prepared to provide a valid USCIS case number, also known as an A-number, when inquiring on the status of a specific case, advises the USCIS.
