I built TunnelBuddy (tunnnelbuddy.net) just for this. I am the same: citizen of one country and resident of another. I have multiple friends and family where I am from. I get them to open tunnelbuddy (nobody needs to sign up), to share a one-off password (like TeamViewer) and I get to access the internet as if I was at their place.

Underneath, it uses WebRTC (the same tech as Google Meet). It is free to use, I just built to fix this problem that I have... I am quite surprised expats only get by using a traditional VPN whose IPs are known by online services...
