The EB-3 visa backlog refers to the waiting period between submitting your application and receiving your green card. Due to annual visa limits, applicants must refer to their "Priority Date" and the monthly Visa Bulletin issued by the U.S. Department of State to determine when they can proceed with their application.
1. Visa quota limits: Each country gets about 7% of the total employment-based visas per year;
2. Number of applicants: Applicants from high-volume countries (including China, India, and the Philippines) may wait longer;
3. Visa category: The “Other Workers” subcategory under EB-3 usually has a longer wait time than “Skilled Workers” or “Professionals”.
Note: If either spouse was born in a country that doesn’t have a backlog, the priority date requirement can be waived.
As of May 2025, the priority date for EB-3 Other Workers (unskilled) born in mainland China is August 1, 2017, which seems to imply an 8-year wait. However, EB-3 backlog movement is not linear but jumpy.
Due to factors like COVID-19, passport delays, and low public awareness, the number of Chinese applicants has sharply dropped since 2017. As a result, the backlog may advance quickly or even jump forward, and the actual wait may be much shorter than 8 years—potentially 4 to 6 years.
Yes. Your spouse and unmarried children under the age of 21 can immigrate with you as derivative beneficiaries. They must file separate applications and meet medical exam and other requirements. Note that the age “under 21” is calculated as the actual age at the time the visa becomes available, minus the time the I-140 was under review (in days).
For example, if your child is 21 years and 5 months old when the visa becomes available, and the I-140 review took 6 months, then: 21 years 5 months - 6 months = 20 years 11 months. In this case, the child still qualifies as “under 21” and is eligible to apply as a derivative beneficiary.
