The U.S. Citizenship and Immigration Services allows applicants to check their status by visiting the Adjustment of Status page where they can select My Case Status underneath the Check My Status headline. Entering the receipt number of the case allows the applicant to check his status online, explains U.S. Citizenship and Immigration Services.
The receipt number is a 13-character unique ID that the U.S. Citizenship and Immigration Services assigns to each applicant to track each individual case. It is found on the notice of action sent by the agency and usually has three letters and 10 numbers, notes the U.S. Citizenship and Immigration Services. There should be no dashes when the receipt number is being entered, but other characters such as asterisks are entered if they are part of the receipt number. This number allows the case status to be checked online.
The other alternative is to call the U.S. National Customer Service Center at 1-800-375-5283, as of 2015, the U.S. Citizenship and Immigration Services states. When speaking with the representative, the applicant needs to provide his name, date of birth, alien registration number and his receipt number. The U.S. Department of State Bureau of Consular Affairs provides a detailed step-by-step process by which applicants learn how to go through the National Visa Center processing. This page contains all information regarding the registration process for the application and how to update the case status.
