I’m not an immigration lawyer and you or your employer should seek legal advice, but it does appear that the so-called Travel Ban 3.0 would block all Syrian citizens from coming to the USA on either immigrant or non-immigrant visas: https://www.acslaw.org/expertforum/trumps-travel-ban-two-years-later/
You may also want to look at this answer which details some loopholes (and the respondent to the second answer says they got a visa): Can a Syrian citizen get a US visa? (regarding the travel ban)
Again, seek professional legal advice rather than internet strangers.
