Only English in the US?

The US Senate voted 63-34 to declare English the national language. One of the requirements for undocumented immigrants to become citizens would be to learn English. Some people believe that passing this kind of legislation will send a strong signal that immigrants should learn English. I have written about this topic many times and will probably do so again in the near future. In the meanwhile you can read articles I wrote about English only in the Japan Times and at La Oferta.
