  3. Current workload at the field office: Occasionally, the Denver CO Field Office may experience an unusually high volume of cases, leading to processing delays.

How to Navigate the Process

Here are some tips and advice for navigating the process at the Denver CO Field Office:

  1. Thoroughly review the forms and instructions: Before submitting your application, ensure you have a clear understanding of the directions and requirements for completing the form. For example, review the annotated N-400 form or the I-485 form to avoid common mistakes.
  2. Submit complete and accurate information: To prevent delays in processing, be sure to submit all required documentation and information without any discrepancies or missing data.
  3. Stay informed of changes and updates: Regularly visit the USCIS website to obtain the most up-to-date information on application requirements, policies, and any relevant changes.

How to Ensure Your Application is Processed as Quickly as Possible

To expedite the processing time for your application, consider the following:

  1. Compile and organize required documentation efficiently: Have all the necessary documents ready to submit with your application, which will minimize the risk of delays.
  2. Look into expedited processing options: Investigate possible options for expediting your process, such as Expeditious Naturalization for certain foreign-born spouses.
  3. Consider mandamus: In some cases where USCIS fails to take action on applications within a reasonable time, applicants may be eligible to file a “Writ of Mandamus” to compel USCIS to take action. However, it’s crucial to consult with an immigration attorney before pursuing this course of action, as it can be a complicated and time-consuming process.
