>As a visa holder you should generally respect the laws of your host country. ... and terms of your visa. >To the extent that the laws of your host allow you to participate in political action you should feel entirely free to. You are taking a risk that a citizen of that country does not. If a citizen gets arrested as part of riot/protest control, they'll get released in a short amount of time. You, as a visa-holder, may get your visa revoked, lose your job and get deported. You may have issues with visa renewal or reentry (because typically visa terms allow for arbitrary revocation and lots of discretion is given to border agents and issuing officer). But it's your life. Take any risk you want.
