Yes sadly there are a lot of jobs that are limited to specific countries or time zones. It’s best to search for your country or time zone using the search on https://himalayas.app/jobs :)
It's not against the site, it's the companies fault advertising as remote. Or mine, understanding remote as something that shouldn't have to do with borders.
I think a big part of it is compliance with local employment laws. There are great companies like remote.com and letsdeel.com that are making it easier to hire people internationally though! :)
