I’m not sure what you mean is hard? Besides uprooting and establishing a new life in a different culture ofc.
To my country a travel visa of three months is automatic/not needed from the US.
A work visa requires proof of employment at a more than minimum wage job, something like a skilled chef, contractor or entry level college grad job qualifies. After two years you can job hop, four years you get a permanent visa, after five you can apply for citizenship.
Requirements at each of these steps is that you can show you have a valid passport, the means to support yourself (and family) financially, are following laws and regulations, and remember to file the paperwork. No tests, no language requirements, just bureaucracy, patience and making a new life.
If you’re in a high demand profession, a work visa takes 90 days to get and is valid for at least two years.
This is for my country, you can typically check with the consulate for whatever country you’re interested in and they will happily inform you.
Is it though?
We have tons of workers in hospitality on work visas (hotels, tourism, restaurants), we have care staff, doctors, IT professionals, project managers, process managers, engineers, management, PhD students (which is an employment here), finance bros, even life coaches on work visa.
In my specific country they also take no extra risk other than having to culturally and institutionally train you.
It’s definitely harder than doing things at home, and scarier, but it’s entirely doable. In four years we’ll see if there’s gonna be another US election, regardless you’re gonna be 4 years older. Either you stay and hope to weather the US, or you go try building something you’ve chosen for yourself.
It’s not for everyone, and it’s a lot more comfortable being with devil you know. But don’t pretend it’s because the process is impossible.
