If i recieve a visa eb-5 can ithen leave the us and continue to work overseas after my initial arrival to validate the visa and how long can you remain outside the USA

Filing an I-526 petition implies an intent to reside in the U.S. Remaining outside of the country for longer than six months may contradict such intent and jeopardize your conditional green card.

Generally, six (6) months. However, because filing an I-526 implies an intent to reside in the U.S., EB-5 investors who intend to travel outside the U.S. beyond the six (6) month period need to be ensure that he/she does not accidentally cause the “abandonment” of his/her LPR status. The same holds true even once USCIS approves an EB-5 immigrant investor’s Form I-829. If you plan to be outside the U.S. for more than a year, you should apply for and obtain a Re-Entry Permit by filing a Form I-131, Application for Travel Document prior to leaving the U.S. An EB-5 investor who is outside the U.S. for more than a year will not be able to re-enter the U.S. with a Green Card alone; the EB-5 investor will need a re-entry permit

In filing the application and actually securing the end LPR card (conditional status), your intention is to remain in the USA; therefore, the is a presumption that you are abandoning your LPR Card if you leave for a time period in excess of 6-months.

You should stay at least 180 days per year in the U.S. in order to be eligible for your conditional green card.
