If you haven’t done so already, be sure to look through my web site for a description of the different visa categories. The “Visa” page and the links from that page provide a very good overview:

After that, feel free to send me an e-mail if you have more specific questions. Once you are ready to apply for your visa, you can schedule either an in-person or telephonic consultation. The consultation will allow me to fully explore all your visa options, as well as explain to you the different visa application procedures. I can then prepare your visa application, as appropriate.
