The Supposed Original Letter

Here's the text of the "supposed original letter" that Tan claims was mistranslated when put into Spanish:

You are receiving this letter because you recently registered to vote. If you are a citizen of the U.S. we encourage you to participate in the democratic process.
However, if you are here illegally or are just a resident with a green card, you should be advised that voting in any Federal Election is a crime and may result in imprisonment, and WILL result in deportation.
In fact, the U.S. Government is in the process of installing a new computer system which will be used to check and verify all new registrants who vote in the October/November elections. Private anti-immigration organizations may also bring a law suit to have access to this new computer system.
Unlike Mexico, there is NO BENEFIT to voting. There is no VOTER CARD in the USA. It is therefore very stupid to vote in any election if you are not a citizen.
Do not pay attention to any politician who tells you anything contrary. They have THEIR OWN INTERESTS. They just want to win elections. They do not care what happens to you.
