I actually did - a bunch of times back when UK was part of EU, and I didn’t have a EU passport myself. Traveling to UK, permanent resident of Bulgaria (EU), Russian passport.

As long as I’m not _employed_ by a company from the country I’m visiting, and stay a month or two, its fine, at least in the Europe. (I’m a contractor employed by BG company with clients in UK) by “Asia” I meant no disrespect but I know little about the legal state of things there so seemed prudent to generalize
