1) I have never had to get an H1B, so take anything I say with a grain of salt

2) sponsorship is more of a commitment (in time at least) than hiring someone without sponsorship, so you might need more than 6 months' professional experience to convince someone to do that

3) remote work might be a lot easier to get now, if you are willing to go back to Europe for a while, and if you've been doing remote work for a given employer then in a year's time they might be a lot more interested in sponsoring an H1B because they will know you're worth it based on having worked with you remotely
