Further to our below blog post, the USCIS today published Q&A on the pending employment-based case inventory.  We link to this for your reference.

The first question that they answer is always what we wonder about, and that is:

Q: Why is the wait so long for my employment-based green card?

A: A visa must be available before a person can obtain an employment-based green card.  Because more people want a green card than there are visas available, not everyone who wants a green card can get one immediately.  Therefore, some people have to wait in line until a visa is available.  The U.S. Department of State (DOS) gives out 140,000 employment-based visas each year.  About 85% of those visas go to people seeking a green card in the United States, while about 15% go to people seeking to immigrate from abroad.  Currently, about 234,000 people have employment-based adjustment of status (green card) applications pending in the United States and are waiting to get a visa.   How long you wait for a visa depends on the supply and demand for your particular preference category, your priority date, and the country your visa will be charged to, usually your country of birth.

Q: What information do I need to have before using the pending Form I-485 inventory reports?

A: You need to know your priority date and your preference category to use the pending Form I-485 inventory reports.  For more information on priority dates and preference categories, see the “Visa Availability & Priority Dates” and “Green Card Eligibility” links to the right.

Q: How do I read the pending I-485 inventory reports?

A: First, click on the link to the report you want to view. Once you click on the link, the report will appear and you will see a series of charts, one for each preference category.  You will see that each chart has different numbers for each month and year.   These numbers show how many green card applicants have priority dates in that month and year.  To figure out how many applicants have earlier priority dates, add all the numbers from all the cells that correspond to earlier months.
