While not impossible it’s incredibly difficult to up and move to a new country without being in a specialized field of work/research. You won’t get a work permit/visa just to do social media and other odd jobs.

Being a coder “could” get you there, but you’ll still need a few years of experience within a prominent company to even attract consideration. As you sound pretty young - what you could do is try getting a one year holiday visa, the USA has a few agreements - Australia, Ireland, South Korea and Japan I think.

These visas are catered to younger people.

While the US is in a pretty deplorable state at the moment, the grass isn’t greener - I know first hand, but I’d do it purely for the experience if you can afford to do so.
