Business
If you move to a foreign country, it is more than likely that at some point you will need to seek professional advice from someone who really understands how the business and legal infrastructure works, especially because legislative systems are a rather complex matter. To speak with a lisenced professional is certainly a wiser idea than struggling with a problem and not having the correct information (and often a sufficient command of the language) to resolve it! Nowadays many more financial and business advisors speak English.
