I see it similarly, whoever comes here can be and should be expected to learn English. And I do not see any reason why we are forced to display lots of stuff in Spanish and English. This is an English-speaking country.
But ... this is a new client and they are located overseas. In that case one cannot expect same and I think that our bureaucrats and the laws should recognize that we are not alone in the world. There are countries where people to not speak English.
So I sent a translation and placed an extra paragraph in both languages underneath, that I translated from the English version "to the best of my knowledge". That ought to do. If some bureaucrat doesn't like that, oh well :-)
