If I withdraw my EB-5 investment before redeployment, how long do I have before I lose my work authorization in the U.S.? I currently have an I-765 and an I-131.
The legal basis for your I-485, I-765, I-131 is the continuation of the I-526 petition and the investment in the project. The withdrawal of the I-526 petition will cause you to be out of status immediately.
USCIS will tell you when they revoke everything, and they will revoke everything. After the revocation, you usually have 30 days to leave the U.S.
Technically, if you withdraw before the completion of the sustainment period - that is, the filing of the I-829 - you lose eligibility and then it's a question of how soon before immigration discovers this.
This would be an issue when you file your I-829 petition to remove conditions.
Discuss with immigration attorney to explore available options based on your circumstances.
