Getting turned down for remote jobs for not being in the right countries...

I’m a little heartbroken here. I want to transition my career to a remote job and been actively applying for positions. I’m awaiting on some processes resolutions but have received a denial from a few ones, including one I really liked … , mostly for the same reason “I don’t currently reside on X, Y and Z country (typically US, Canada, UK and Germany).

Do you have some advice to share about this? Thanks in advance.
