You have a pending I-485 and both EB-2 and EB-3 I-140 petitions. EB-2 is now current. Can you switch the I-485 back to EB-2? You can ask, but the switch is not automatic. USCIS may approve or deny the request. [1]
Two I-140 petitions can coexist, but one I-485 follows only one petition at a time. USCIS calls switching that petition a transfer of underlying basis. This article calls it a switch. It is separate from the AC21 rules for changing jobs. [1]
Which I-140 supports the pending I-485?
Check which I-140 was named when the I-485 was filed, and whether USCIS approved a later switch. A faster moving category does not replace it automatically. To ask for a switch to an approved EB-2 I-140, write a letter naming the target I-140 and the pending I-485 receipt number. Include the receipt and proof that you qualify for the new category. The I-485 must still be pending, the new category must have a visa available when you make the request, and your earlier adjustment eligibility must not have lapsed. Usually you do not need a new I-485 or another I-485 fee. Check current mailing instructions and case specific materials with counsel. [1]
Which priority date applies after the switch? Generally, it is the date attached to the replacement I-140. If you switch back to EB-2, check the priority date recognized on that EB-2 petition. Do not assume the EB-3 petition's date follows the I-485. EB-1, EB-2 and EB-3 petitions may retain an earlier date when the rules allow it. [1]
What if EB-2 becomes current after an EB-3 downgrade?
You can ask, but approval is not guaranteed. USCIS's FY2022 FAQ discusses a specific case: the EB-2 priority date is current under Final Action Dates and a separate EB-3 petition is pending. USCIS says the pending EB-3 alone does not block a request to switch the pending I-485 to another approved I-140. That answer does not mean every case can switch at any time. USCIS still checks the pending I-485, continued eligibility, and visa availability on the request date. [2][1]
What does Supplement J do?
The letter says which I-140 should support the I-485. Supplement J confirms that a job offer still exists or, when eligible, requests a job change. Filing Supplement J alone does not replace the letter. For a switch to a previously approved I-140, USCIS says a new Supplement J is generally needed to confirm the offer. NIW and EB-1A applicants do not need it for this job offer requirement. Check the current form, signatures, and your case with counsel. [3][4]
If I filed on an NIW and then left my job
An NIW filer does not file Supplement J, and there is no “wait 180 days before changing jobs” rule for it. USCIS's I-485 instructions (edition 09/18/26) say people seeking or granted a National Interest Waiver, and people in the extraordinary-ability category (EB-1A), do not need to file Supplement J, because these categories are not tied to a specific job offer. The “job portability after 180 days” rule (INA 204(j)) is for categories that require an employer job offer.
That does not mean “work at anything.” The same instructions say a self-petitioner must intend to work in the occupational field specified in the I-140, and, unless you filed the I-485 at the same time as the I-140 or while the I-140 was still pending, must provide a signed statement confirming that intent.
The instructions give no further test for what you may do after leaving, how long a gap is acceptable, or whether to add that statement. Ask your immigration lawyer.
Does a transfer put the case in a “black hole”?
We found no USCIS source establishing that a transfer automatically loses a case or adds a fixed number of months. USCIS does say that matching the replacement petition to the I-485, collecting evidence, and retrieving files may add processing time; a request made too close to final adjudication may be too late. Keep proof of submission and monitor notices. Withdrawing the original I-140, changing employers, or including derivatives can affect eligibility; ask your immigration lawyer about your own facts.
