How can my child enroll in a U.S. college with a pending EB-5 I-485?

If you have a pending EB-5, you need to argue that his date froze upon filing of the I-485. But I understand you have likely filed under a Date for Filing and now with Chinese and Indian retrogression these children are not safe. It may be hard to get an F-1 visa with a pending I-485 but many consulates have been sympathetic and provided he has an advance parole, there may not be too much risk in applying. The other option may be to see if you can withdraw your investment and top it up with a new investment and file a new I-526 under a fast track set-aside category that is current.

Your child will be able to enroll in college by using his I-485 receipt notice to confirm that he is lawfully in the U.S. with a pending I-485 application. The act of filing form I-485 serves to satisfy the "sought to acquire" requirement, which will freeze his age and prevent him from aging out.

What nonimmigrant status is your son on now? Yes, your son can enroll in college with the EAD from a pending I-485. The question for the college becomes whether he is eligible for in-state or out-of-state tuition.
