Por Favor.  I am an architect with preservation and sustainable design experience and some regional and city planning experience.  If you will ask your question in USA "English", so that I can fully understand it, I will try to answer it.  I respect your right and obligation to preserve your cultural heritage, and encourage you to do so.  Ich kann Deutsch sprechen und auch Comanche...my two heritage languages, but I do not try to make others speak them for day to day 'business" and life.  One primary language helps build national unity, efficiency, and security.  This, obviously, is my personal opinion and freedom of speech is still a right here unless the supreme court has changed it recently. 

English es la Lingua con los Estados Unidos...as you probably know, but possibly do not like.
