What do you do with visa related questions(here and here for example) that don't show any research ? Other than quote an embassy website or comment with suggestions.

Most embassies/consulates have websites. This related question proposes to close as unclear, that doesn't quite apply here as the question is clear but the user hasn't looked before asking.

I feel downvoting new users who may not be familiar with the site wouldn't be a great first experience that invites them to return.
