Looks like I have to switch my life's passion to engineering pretty much. I guess if I can do it it would be worth it.
Welcome to UKY!
Unfortunately, as mentioned, the UK is very anti-immigration at the moment so it is very difficult to secure a work visa.
IMO, I wouldn't base your education and career on something that may give you the opportunity to get a visa for the UK. If you are genuinely interested in a specific subject that happens to be in demand and on the shortage list, then by all means, go for it! But remember that UK immigration changes, and if you only choose a career path solely for immigration (and not because you are genuinely passionate about it), you could find yourself in a situation where you're working in an area you don't like, and it didn't help you get a visa either.
You could find that by the time you qualify for an occupation on the shortage list now, when you want to apply for a visa, that skill is no longer on the list and it won't help you to get a visa after all. Or, you could obtain a visa to live and work in the UK and not end up qualifying for permanent residence after all those years if the rules change during your stay.
If you want to get into a career that may be beneficial in getting a UK visa, that's great and worth a shot, but make sure it's a career you would be happy with no matter where you are.
