International Remote Work

Has anyone here successfully worked abroad while employed by a U.S. company?

I’m a U.S.-based employee working for a big four, but I sometimes need to spend extended periods outside the country (visiting family, etc.). My employer has a strict “U.S.-only” remote policy, and I’ve already been told “no” when I asked about exceptions.

What has worked (or not worked) for those who may have tried working internationally.
