Over 4,600 green card recipients resided in Oklahoma in 2019 (Statista). The applications of these recipients and all others, except those seeking asylum, are processed by the U.S. Citizenship and Immigration Services (USCIS). The USCIS is under the Department of Homeland Security (DHS), and the federal agency operates through its physical locations, website, and phone service.
As an immigration applicant, your interview is held at a field office of the USCIS. The number of field offices in a State varies. Instead of cities or States, the agency uses a system of Districts and Regions. Districts can have jurisdiction over counties present in multiple states. The Districts are divided into 4 regions: Northeast, Southeast, Central, and Western.
The Oklahoma City Field Office
The office is located in the Dallas District and Central Region. Its address is as follows:
Oklahoma City (OKC) 4400 Southwest 44th Street Suite A Oklahoma City, OK 73119
The field office services the entire State of Oklahoma.
Case Processing Time
The processing time for your case will depend on where your case is processed and what type of application form you submit. The USCIS provides current processing times that you can search by providing your form and office. The agency also has a separate section where it displays the historical national median times for all of its offices. Here are the processing times for naturalization and citizenship applications:
- Naturalization (N-400): 10.5 to 14 months
- Citizenship and Issuance of Certificate Under Section 322 (N-600K): 10 to 22.5 months
- Certificate of Citizenship (N-600): 6.5 to 14.5 months
The above-mentioned times are calculated using a new method, which, according to the agency, improves accuracy and is easier to understand. To understand this method, let’s consider the example of the N-600. The 6.5 months is the duration for processing 50% of the cases, and the 14.5 months is the duration for doing 93%.
Scheduling an Appointment
Walk-ins are not available at any USCIS location so make sure that you have an appointment. If you’re inside the U.S., you can make an appointment by calling the agency. If you are in Saipan or Guam, you can set the time by messaging or calling the agency. If you’re outside the U.S., you can choose the online system to find the nearest international office.
After making your appointment, you can change or cancel it online and also reprint the application letter, if needed, from the following page. However, the option to change your appointment online is only available to international users. The online option you have with a domestic appointment is to cancel it. To take these actions, you will need your appointment confirmation number and your PIN.
The USCIS provides several form filing services online. The agency has a fee calculator that provides you the fees for filing and biometric services. This is a useful tool because the agency adjusts its fees periodically.
Several forms are available for online submission. However, the agency may require you to submit a paper version along with the online in some cases. The steps to file a form online are available in the following section.
