If I want to change my status from a visitor, what do I do? 7 Answers as of October 24, 2011

Not clear from your email what is the immigration status of your wife. If she is a US citizen, you may adjust status to a permanent resident.

You can file for adjustment of status.

If you have not overstayed the date on your I-94 card, you can file an I-539 application to extend status. USCIS must receive the application before the date on the I-94 card.

You use form I539 to request an extension. Given the importance of correct filing and also the subtle ramifications that this decision can have on future ability to obtain visas or enter the US, you may also want to have a full consult with a competent immigration attorney before hand.

The process depends upon what type of visa you wish to change your status to. If you are looking to extend your visitor status or change to another non-immigrant visa, you can file an I-539. The supporting evidence you will need depends upon the specific request. If you are looking to change your non-immigrant visa to permanent residence than you should not enter the United States on a non-immigrant visa. The fact that you use a non-immigrant visa to enter the United States with the intent to immigrate can be detrimental to your case.

You first of all need to qualify for a particular status. It depends on the requirements for that status to determine what needs to be done to change your status. You should consult with an experienced immigration attorney.
