Risks of Employer Withdrawing I-140 Before 180-Day I-485 Pendency for AC21 Portability

Summary

Immigrants seeking U.S. permanent residency via employment-based routes face a significant risk if their sponsoring employer withdraws the I-140 petition prematurely. AC21 portability, which allows applicants to change jobs while their I-485 is pending, critically requires the I-485 to have been pending for at least 180 days and the I-140 to remain approved throughout that period. If the I-140 is withdrawn before this 180-day mark, the underlying basis for the I-485 is invalidated, making AC21 portability impossible and potentially jeopardizing the entire green card application.

The ability to "port" an employment-based green card application to a new employer under AC21 (American Competitiveness in the Twenty-first Century Act) is a crucial protection for many immigrants. However, this portability hinges on specific timing requirements. A core condition for AC21 portability is that the I-485 Application to Register Permanent Residence or Adjust Status must have been pending for at least 180 days, and the underlying I-140 Immigrant Petition for Alien Worker must have been approved and remained valid through that 180-day period. If the sponsoring employer withdraws the I-140 petition *before* the I-485 reaches the 180-day pending mark, then the essential foundation for the I-485 application is eliminated. This means the I-485 application is effectively nullified, and the applicant loses the ability to utilize AC21 portability.

This policy has profound practical implications for immigrants who might consider changing jobs shortly after filing their I-485. Without the I-140 remaining approved for the initial 180 days of the I-485's pendency, applicants cannot leverage AC21 to switch employers without restarting their entire green card process, potentially losing their priority date. It underscores the critical need for careful planning and communication between applicants and their sponsoring employers, especially when contemplating a job change. Immigrants must be acutely aware of this 180-day threshold and understand that a premature I-140 withdrawal can entirely derail their path to permanent residency.

Background

AC21 was enacted in 2000 to provide greater flexibility for employment-based green card applicants, primarily by allowing them to change jobs or employers while their I-485 applications were pending for a significant period. This provision aimed to prevent applicants from being "tied" to a single employer for many years due to lengthy green card processing times.

Who This Affects

  • Employment-based green card applicants who have filed an I-485 face the risk of their permanent residency path being disrupted if their sponsoring employer withdraws the I-140 prematurely.
  • Sponsoring employers should understand the implications of withdrawing an I-140 petition, particularly for employees whose I-485 is still pending and has not met the 180-day threshold.
  • Immigrants contemplating a job change while their I-485 is pending must be aware of the strict 180-day rule before switching employers to ensure AC21 portability remains an option.

What You Should Do Now

  • Consult with an experienced immigration attorney to seek personalized advice regarding your specific I-485 and I-140 status before making any employment changes.
  • Carefully track your I-485 pendency period to ensure you know the exact date your I-485 was filed and when it will reach the 180-day mark.
  • Maintain open communication with your sponsoring employer to discuss any potential I-140 withdrawal plans and understand their impact on your green card application.

Key Takeaway

For AC21 portability, it is absolutely critical that your I-485 application has been pending for at least 180 days AND the underlying I-140 petition remains approved throughout that entire period.
