In the letting of public contracts, preference shall be given to resident contractors, and a nonresident bidder domiciled in a state, city, county, parish, province, nation or political subdivision having laws granting preference to local contractors shall be awarded Mississippi public contracts only on the same basis as the nonresident bidder's state, city, county, parish, province, nation or political subdivision awards contracts to Mississippi contractors bidding under similar circumstances. Resident contractors actually domiciled in Mississippi, be they corporate, individuals or partnerships, are to be granted preference over nonresidents in awarding of contracts in the same manner and to the same extent as provided by the laws of the state, city, county, parish, province, nation or political subdivision of domicile of the nonresident.
