I got my EB-5 conditional green card, how can my wife also get it?

If you were married at the time of getting your green card she can apply via a derivative application or via a petition. A derivative application would be much faster.

If you were married before your permanent residency was approved, she can file either as a follow-to-join at the consulate you were interviewed or by adjusting status in the U.S. if legally here and in status.

She was not included in your application as a dependent? That would have been the way! But I understand that there are circumstances where one can travel before another can travel. She can follow to join you now that you have yours handled.

Assuming your wife is admissible and otherwise eligible to immigrate to the United States, she can follow to join you without the need for filing a separate petition. Depending on where you received your conditional permanent residence (adjustment of status vs. immigrant visa processing), and depending on where she is presently, you may have to file some additional forms and paperwork to get her case started.

Depending on whether you are in the U.S. or out of the U.S., you may file for her as well.

It is hard to answer this question given the facts you presented, but it seems you were not married at the time you applied for an immigrant visa/filed for adjustment of status. And if that is the case, then no, she cannot derive benefit from your EB-5 petition. At this time, you can petition for your wife as an LPR; F-2A is current for all countries so if you are both in the U.S., you can follow one-step adjustment.

You can file an I-824 with the application for her so she can get it faster.
