How can an approved EB-5 investor schedule the filing of a re-entry permit and removal of conditions while living outside the US?

You can only file a reentry permit while physically in the US and you should take steps to establish residence in the US by filing taxes and having a home because reentry permit adjudications are slow.

You have an involved situation. You need a consultation appointment with an immigration attorney.

You must be in the U.S. to file each of these documents but can then leave. You may use a c/o address if more convenient for fingerprinting purposes. We suggest using counsel address for delivery of documents.

Reentry permit application must be filed while you are present in the US and you will need to attend a biometrics appointment when scheduled by USCIS. A reentry permit will be limited to your conditional green card validity period. You are still required to maintain ties to the US. I-829 can be filed while outside the US. Consult your immigration lawyer for further details.

Yes, this is possible. Need to do some back-and-forth travel, which is easy from Canada. Your attorney will walk you through the process.

Reentry permit applications must be filed while the green card holder is in the US. I-829 (removal of conditions) can be filed while abroad. Sounds like you should seek specific advice on making sure you do not abandon your green card status.

There may be some way to do it, but my recommendation is not to try this. There are many things that can go wrong.
