US immigration? If I live past tomorrow, I want to leave the US. Idk how to even start.
That all being said, as some sibling comments put it, the grass really always is greener on the other side. As a dual citizen (US-EU) I'm perfectly happy to stay in the US. Some of my family moved back and immediately came to deeply regret it. (Specifically wrt your note about living past tomorrow, I promise you I wouldn't be attending my grandmother's funeral today if she had stayed in the States.) Maybe you should take a full inventory of the advantages and disadvantages of your current and target states before devoting many long hours to the immigration process.
Personally I am investigating how could I move to the US...
Even though I am very interested in moving to the US, realistically that will remain only a plan.
I will warn you, though: salaries in the software sector are generally much lower abroad, though the cost-of-living is generally lower too, so it's not necessarily that bad.
That is the method to obtain citizenship for most without means is you must act without permission and then run down the clock.
The US immigration authorities do occasionally do raids on employers that are known to employ lots of illegal immigrants (which can be people who simply walked over the border, or people who overstayed a visa). It's not unenforced. For people in higher socioeconomic strata that blend into the population better, it's not that well enforced probably because it's just hard to find them, and local law enforcement doesn't deal with it.
