this info is over 30 years old so I don’t know if the scam is going on today. I lived in Alaska in one of the fishing villages. Processing fish at the canneries is labor intensive and when they get product in you work till the product is all processed because there is a limited time that fish will stay fresh before either freezing it or canning it...this is hard work and never enough workers. the town I lived in had 3 canneries operating and if you looked at coastal canning operations there are usually 3 operating in the summer. the canneries would hire illegals take a fake or stolen social security number on the application. the person would start working that day at the cannery. the cannery would then slow walk the paperwork sending it in as late as they could get away with it. after 6-7 weeks it would come back from the government as being a fake number and the worker would be fired, that worker would then go over to the other cannery and immediately get hired and the paperwork shuffle would happen again. the fishing season is short and after being fired from the 3rd cannery it was over. that illegal worker would come back the next year and the same paperwork shuffle would be played again.
Which proves that the government sticking its nose in industry does not cure problems....it only creates a different set of problems, usually worse.
