After completing the Step 2 of the United States Medical Licensing Examination (USMLE), you can apply for medical residency programs in the United States. Here are the steps to follow:

1. Register with the Electronic Residency Application Service (ERAS). ERAS is a centralized application service that allows medical students to apply for residency programs across the United States.
2. Compile your application materials. Your application should include your personal statement, letters of recommendation, transcripts, and USMLE scores.
3. Research residency programs. Use resources such as the Accreditation Council for Graduate Medical Education (ACGME) website and FREIDA Online to find residency programs that match your interests and qualifications.
4. Submit your application materials through ERAS. You can apply to multiple residency programs using the ERAS system.
5. Participate in the National Resident Matching Program (NRMP). The NRMP is a system that matches applicants to residency programs based on their preferences and the preferences of the programs.
6. Attend residency interviews. If you are selected for an interview, attend the interview and use the opportunity to learn more about the program and showcase your qualifications.
7. Receive your residency match results. Match results are typically released in March, and you will be notified if you have been matched to a residency program.

After you have been matched to a residency program, you will need to obtain a medical license in the state where the program is located. The requirements for obtaining a medical license vary by state, so it is important to research the specific requirements for the state where you will be practicing.
