How can I get EB-5 and L-1A with the same enterprise?

Everyone would have to independently qualify for their own process, but if prepared correctly, this may be possible. It is at least worth considering.

Yes, if you invest the correct amount of capital and create at least 10 new jobs in a new business, this could be the basis for both an L-1 and an EB-5. And if the position is managerial, you might also qualify for an EB-1 managerial transfer green card.

I do not see why that would not work in theory.

It is possible to utilize the L-1A immediately to set up your company in the U.S. Then, you may have an option for EB-1C as a multinational executive/manager, or EB-5. The benefit with having the L-1A visa is that there is dual intent, which means you can pursue permanent residence while also being in the U.S. temporarily for work. More information is needed to be able to address your scenario in detail.

If the entity meets the L-1 qualifications, you can obtain both the L-1 and the EB-5 visas under the same enterprise.
