After trying with that method, I experimented with many other routes. Most expect me to already have a work visa. I've been trying since March. I rewrote my résumé twice. I updated my LinkedIn. I asked recruiters for help. I put side projects on the web to try to get attention. I asked friends who I worked with at a local company when I was there before. I found random people on Github and offered to work for free on open-source projects just to get an introduction. I contacted computer repair shops and asked them to put up posters advertising data migration services that I could do with my old Apple II. Nothing has worked. Now I'm spamming every company on the Accredited Employers list (whether in the tech industry or not), just to try to get some new ideas of how to approach the application process in that country.
