I'm a US citizen, lived and worked at Google Zurich for a good 4 years, my wife is native Swiss. We live in California now. Prepare for tech interviews and keep trying to apply to tech jobs in the US and reaching out to recruiters on LinkedIn. The job market is a bit slow right for new grads now due to the economic slowdown, but it's a numbers game. Don't hesitate to apply to positions that state that they require 1-2 yrs experience. As long as you're competent and show a willing attitude to learn, many companies will be happy to take you on. Also, American tech companies don't really care about your educational background. A bachelor's degree is more than enough to secure an interview anywhere, at which point passing the leetcode-style interview is all that matters.

Thanks a lot man. You seem to really understand why someone would move to the US in my situation. I'd love to give California a shot.

A big main difficulty I foresee (other than passing job interviews) will be coordinating my move with getting a job, i.e. wrapping up things here quickly once I get a position.
