I'm in the same boat you are (Unity AR/VR developer looking for a new job / relocation). I've had the best luck searching for very specific roles / job titles that fit me and reaching out to companies I have a special / good fit with. It's been working well, and serious companies have already begun offering to fly me out for the final interview. This is standard.
