1. Confirm Eligibility: Ensure that you meet the following criteria to sponsor your parents:

• You must be a US citizen and at least 21 years old.
• Your parents must qualify as immediate relatives, with no numerical limits for green card availability.

2. Understand the Process: Familiarize yourself with the overall process of sponsoring your parents for green cards:

• File an immigrant visa petition (Form I-130) on behalf of your parents.
• Once approved, the National Visa Center (NVC) handles documentation and fee processing.
• Your parents will either go through consular processing or apply for adjustment of status, depending on their location.

3. Gather Required Documents: Collect necessary documents to support your petition, including birth certificates, proof of relationship, marriage certificates, divorce decrees (if applicable), and evidence of financial ability to support your parents.

4. File Form I-130: Complete and file Form I-130, Petition for Alien Relative, along with required supporting documents. Pay the filing fee and submit the application to the appropriate USCIS office.

5. Monitor Application Status: Regularly check the USCIS website for updates on your application status. You’ll receive a receipt notice and later an approval notice, with processing times varying.

6. NVC Processing: Once approved, the petition is forwarded to the NVC for further processing. Pay necessary fees, submit required forms and supporting documents, and complete the Affidavit of Support (Form I-864).

7. Consular Processing or Adjustment of Status: Depending on location, your parents will undergo consular processing or apply for adjustment of status. Prepare for interviews and ensure all necessary documentation is provided.

8. Attend Interviews: Both consular processing and adjustment of status require interviews. Prepare your parents for the interview and attend with them or ensure they are well-prepared if attending alone.

9. Receive Green Cards for Parents: Upon successful completion of the interview, your parents will receive their green cards, granting them permanent residency in the United States.

10. Post-Arrival Responsibilities: Guide your parents through necessary post-arrival responsibilities, such as understanding their rights and responsibilities as permanent residents, obtaining a Social Security Number, driver’s license, and exploring resources for English language learning and cultural integration.
