When you are applying a visitor visa to the United States. You must demonstrate that this visa is for a short period of time. Immigration officials view visa applications as a intending immigrant. That is why you must demonstrate that you are for real.
There are certain ways that you could prove you will only be in the country for approximately 90 days or six months. On your application state clearly the purpose of your trip such as for business, pleasure , or medical treatment. Have evidence of funds to cover all costs while you are in the country. Have some type of proof that you will be returning to your home country, such as ownership of a home, employment or a business in your home country. If you can demonstrate these requirements, you should have no problem meeting the necessary requirements for a visitor visa. You can obtain more information by going to the State Department website.

The coolest stuff is the dual camera. It has a back camera capable of video recording, HD (720p) up to 30 frames per second with audio; still camera with 5x digital zoom. While the front camera: has the same feature: Video recording, VGA up to 30 frames per second with audio; and VGA-quality still camera.
When it comes to accessibility, iPad2 has Voice Over screen reader which I use when I listen to the bible instead of reading it. It support for playback of closed-captioned content. Assistive Touch interface for adaptive accessories and has an awesome full-screen zoom magnification. The fonts are large and has white on black display plus, a left and right volume adjustment. So far, I am happy for my iPad 2.
