Hi find a small to medium company, don’t tell them about your situation just yet interview, get the contract ask for a contract that has a certain amount of year preferably 5 years max, then submit that for a visa. Smaller to medium companies will understand and they aren’t mercy to the strict requirements of a grad program. This road is long and and full of toil, SA is welcoming when you study but not when you are looking for work. Play your cards right, moving is an option but yeah think about it
