At what point in the EB-5 process can I withdraw from my investment?

Technically, once you file the I-829 you can exit the investment, but your investment documents may have other arrangements that you agreed to when signing them.

You need to review the project documents you signed to get these answers.

It will all depend on the terms of the agreement you signed for the project, but you can generally recover your investment as soon as the I-829 is filed.

There are two questions here. The first is how can you legally redeem your funds, and the other is what did you agree to. Legally, USCIS has clarified that upon filing the I-829, the funds can be redeemed. However, the subscription and other agreements regulate the terms of repayment.

You can get your investment back after your 2-year conditional residency is up without jeopardizing your green card. However, when you can get your investment back is also subject to the offering documents you sign and whether the project has enough cash to make the payment.

It makes sense to me that you wait until you get your green card.

It is safest to withdraw after you receive your permanent green card, but the law/regulations require sustainment of your investment only for the conditional period.

Check with your project (I’m assuming you mean when you are eligible for repayment here). Each project has different repayment terms. Some allow you to be repaid once the 2-year conditional period is over. Some... not so much depending on if funds have been redeployed, if they require ALL investors to complete the CPR process first, etc. So check with them first.
