1) What kind of applicant profile fit the EB-5 visa best?

The applicant has to make up their mind that they would like to move to the United States. Those looking for a plan B should not consider the EB5 visa. If they do not move to the United States within a reasonable time after receiving the green card, the authorities would likely confiscate it.

Of course, they need to have the required investment amount and related fees in liquid funds to proceed. Illiquid funds are ok as long as they are confident that they will liquidate their assets in a reasonable amount of time to make the required investment in one shot.

Typically, unless they deposit the fund with the escrow agent of the regional center, the I-526 application process cannot proceed. Of course, the investor will need to provide the source of funds for the funds he/she intends to use as well.
