How will the travel ban impact my EB-5 application?

Dual citizens are exempt.

The EB-5 category does not explicitly exempt from the travel ban restrictions and a waiver application may be required if restriction applies. A waiver process is on a case-by-case basis.

Generally, petitioners are judged according to their country of birth. Even though you are a Syrian national, your petition is likely to be adjudicated as a Saudi Arabian where you were you born, rather than as a Syrian. Advisably, consult your EB-5 attorney prior to taking further action.

People who have dual nationality/citizenship with a non-restricted country are not affected by the ban, so long as they travel on the passport from the other country, nor will it affect your ability to process for EB-5.

You were born in Saudi Arabia. Given this and assuming you carry the Saudi passport, your visa will be attached to Saudi Arabia, rather than Syria. You may have issues given the dual passports.

As a Syrian-born national but also a citizen of Dominica, you should not be subject to the Syrian travel ban. You will have no difficulty in applying for and filing an EB-5 investor petition on Form I-526. Once approved, you would then be eligible to apply for your immigrant visa at the appropriate consulate abroad. That could be in Dominica or more likely at the American embassy in Abu Dhabi. Again, you should not be subject to the travel ban.
