Emigrate to U.S?

I worked in the USA when I left school, with the Young farmers club , international student exchange visa JI program, one lad went out ,met a lady, and didn’t come back.
I looked at the harvest teams, of driving combines or tractors covering most of the States.
I was sent to a dairy farm in Michigan then to a tree plantation in Fort Lauderdale.
They are not tolerant of giving green cards to live and work there, just by getting married, maybe years ago, but not now.
There is the cruise ship option, from Port Everglades Miami they go to all of the Caribbean and South America , to get work.
