Any spanish speakers here?

Hello everybody, I'm Al and this is one of my first forays on the Internet with the help of my granddaughter Emily. I was recently forced into retirement following several years in the railroad industry. I am unable to get used to this, so I'm trying to keep busy on the Internet. A short while ago, I met this fellow at the community center and, long story short, somehow became interested in what he was working on (helping immigrants to deal with life in America). I thought maybe that's my calling, aiding other people. However I require a little help myself when it comes to the Internet. I'm trying to determine what this visa a estados unidos site is supposed to be about. I have tried a few language translators but they do not make sense to me. I i understand that a few of you in here know some spanish, so if you can help me out or send me in the correct direction for a decent online translator I would truly appreciate it. I apologize if the message doesn't go here, I'm going to have to blame my grandaughter for that :). The site is http://www.visaestadosunidos.info if you can help me out. All the best.
