What is AC21 106(a)?#

AC21 106(a) is a federal law that amends the Immigration and Nationality Act (INA) to provide job portability for green card applicants in the employment-based category. Prior to AC21, applicants were strictly tied to the employer who sponsored their immigrant petition (I-140). If they left that employer before receiving a green card, their application could be denied.

AC21 106(a) relaxes this rule by allowing applicants to change jobs or employers after their I-485 (adjustment of status) application has been pending for at least 180 days—provided the new job is in the same or similar occupational classification as the one listed in their approved I-140 petition.

In short, AC21 106(a) gives applicants flexibility to pursue career growth without sacrificing their green card eligibility.

Key Requirements for Job Portability Under AC21 106(a)#

To qualify for job portability under AC21 106(a), applicants must meet three core requirements:

1. Pending I-485 for At Least 180 Days#

Your I-485 application (adjustment of status) must have been pending with USCIS for a minimum of 180 days. The "pending" period starts from the receipt date of your I-485, not the date your I-140 was approved.

2. Approved I-140 Petition#

Your employer-sponsored I-140 (immigrant petition) must have been approved before you change jobs. If your I-140 is still pending when you switch employers, AC21 106(a) does not apply—you may need to restart the process with a new employer.

3. New Job in "Same or Similar" Occupational Classification#

The new job must be in the same or similar occupational category as the job described in your approved I-140. USCIS evaluates this based on job duties, skills, education, experience, and the Standard Occupational Classification (SOC) code (more on this below).

When Can You Use AC21 106(a)? The 180-Day Rule#

The 180-day waiting period is a critical threshold for AC21 106(a). Here’s what you need to know:

• Start Date: The 180 days begin on the date USCIS receives your I-485 application (check your I-485 receipt notice for this date).
• I-140 Approval Timing: Your I-140 does not need to be approved before the 180-day mark. However, if your I-140 is denied before the 180-day mark, AC21 portability will not apply, and your I-485 may be denied.
• Employer Withdrawal of I-140: If your original employer withdraws the I-140 after your I-485 has been pending for 180 days, AC21 106(a) still protects your application. USCIS cannot revoke your I-485 based solely on the employer’s withdrawal in this scenario.

Defining "Same or Similar" Occupation: What USCIS Looks For#

The most subjective—and often confusing—part of AC21 106(a) is determining whether a new job is "same or similar" to the one in your I-140. USCIS evaluates this using several factors:

1. Job Duties and Responsibilities#

The core duties of the new job must align with those in the original I-140. For example:

• A software engineer (SOC code 15-1251) moving to a "senior software engineer" role is likely similar, as the duties (coding, debugging, system design) remain the same.
• A software engineer moving to a marketing manager (SOC code 11-2021) is not similar, as the duties (campaign strategy, client relations) are drastically different.

2. Skills, Education, and Experience#

The new job should require the same or comparable skills, education, and experience as the original role. For instance, a registered nurse (SOC code 29-1141) with a bachelor’s degree cannot switch to a physician (SOC code 29-1060), which requires a medical degree and residency.

3. Standard Occupational Classification (SOC) Code#

USCIS often references the SOC code, a system used by federal agencies to classify occupations. Jobs with the same SOC code are almost always considered similar. Even jobs with different but related SOC codes (e.g., 15-1251 for software engineers and 15-1252 for web developers) may qualify if duties overlap.

Example Scenarios:#

• Acceptable: A mechanical engineer (SOC 17-2141) moving to a civil engineer (SOC 17-2051) role, as both require engineering degrees and design skills.
• Not Acceptable: A teacher (SOC 25-2031) moving to a sales representative (SOC 41-4011), as skills and duties are unrelated.

Step-by-Step: How to Change Jobs Under AC21 106(a)#

If you meet the requirements, follow these steps to change jobs without jeopardizing your green card application:

1. Confirm the 180-Day Pending Period#

Check your I-485 receipt notice to ensure 180 days have passed since USCIS received your application.

2. Verify the New Job is "Same or Similar"#

Review the new job’s duties, SOC code, and requirements. Compare them to your original I-140 job description. When in doubt, consult an immigration attorney to assess similarity.

3. Notify USCIS (If Required)#

USCIS does not require formal notification of a job change under AC21 106(a). However, if USCIS requests additional information (e.g., an RFE or interview), you must provide evidence of the new job, such as:

• A job offer letter detailing duties, salary, and start date.
• Pay stubs from the new employer.
• Proof of the new job’s SOC code and alignment with the original role.

4. Update Your Address with USCIS#

If you move due to the new job, file a Form AR-11 (Alien’s Change of Address) to keep USCIS updated. This ensures you receive critical notices.

5. Keep Detailed Records#

Maintain copies of all documents related to the job change, including the job offer, employment contract, and performance reviews. These may be needed to prove the "same or similar" occupation if USCIS questions your application.

Common Pitfalls to Avoid#

Even with AC21 106(a), mistakes can derail your green card application. Watch for these pitfalls:

• Changing Jobs Before 180 Days: Switching employers too early invalidates AC21 portability. Wait until your I-485 has been pending for 180 days.
• Assuming "Promotions" Are Always Similar: A promotion with drastically different duties (e.g., a software engineer becoming a project manager) may not qualify.
• Ignoring I-140 Revocation Risks: If your original employer revokes your I-140 before the 180-day mark, your I-485 could be denied.
• Failing to Document the New Job: Without evidence of the new job’s duties and alignment with the original role, USCIS may reject your portability claim.

Conclusion#

AC21 106(a) is a powerful tool for green card applicants, offering flexibility to pursue career opportunities without sacrificing their path to permanent residency. By understanding the 180-day rule, "same or similar" occupation requirements, and proper documentation, you can navigate job changes confidently.

Always consult an experienced immigration attorney before making major career moves during the green card process—they can help ensure compliance with AC21 106(a) and protect your application.
