Iraq
Business visit visa / Work visa
While the Iraqi immigration system is complex, it is well structured. Foreign nationals who seek to enter Iraq for business visits require either a visit visa or a visa-on-arrival, depending on their nationality. Visit visas allow a single entry into Iraq within one month of the visa issuance and permit a stay of up to 30 days, while visas-on-arrival allow a single entry into Iraq for up to a 15- or 30-day stay.
Generally, foreign nationals entering Iraq to perform hands-on work or who sign a contract with an employer in Iraq require an employment visa. They must also obtain a multi-entry visa to hold legal residence and register with the Ministry of Labour to secure a work permit. Foreign nationals who need to access any oil field must obtain relevant approvals and security clearance from the Ministry of Oil.
Note that immigration processes in Iraqi Kurdistan differ from those in the rest of the country.
