Details worth checking

Complete Applicant's Legal Name

Providing a complete and accurate legal name is crucial to avoid processing complications. Missing parts of your name can lead to discrepancies and delays during application assessment.

Include Alien Registration Number

Omitting your Alien Registration Number, if applicable, can result in significant delays or rejection of your application. This number is essential for tracking your immigration status.

Correct Date of Birth Format

Using an incorrect date format can lead to processing errors. It is essential to adhere to the specified format (mm/dd/yyyy) to avoid misinterpretation.

Complete Medical Professional Information

Incomplete details about the certifying medical professional can delay application evaluation. Ensure all required information, such as name, license number, and contact details, is provided.

Licensed Medical Professional Verification

Only U.S.-licensed medical professionals can certify your form. Incorrect or missing licensing information can invalidate your application.

Thorough Instruction Review

Skipping the instructions can cause errors and omissions in your application. Understanding the guidelines ensures all information is accurate and complete.
