Will non-english speaking visitors to a site recognize Google"s translate drop-down, even if it's in English?

I'm building a site for a client that does business globally. There current site does not have a translate option and I believe (after analyzing their Adwords data), that they are missing a great deal of opportunities. I installed a Google translate widget that works like a charm, the only problem is that we're concerned that it won't be recognized as what it is, since the field containing the "translate" text, is in English itself. Do internet savvy users that don't speak English typically understand what the box will do? Would they typically check the contents of a drop down box labeled with Google's logo? Thanks!
