Hope someone can offer advice. I would like to extend my B2 visa in USA for another 6 months. I'm married to an American but I had planned to visit & return to SA. While I was here on holiday my husband & I have decided that we would like to stay and I would therefore need to apply for a green card. I have been told that the process can take some time and I only have 1,5 months left before I have to leave the USA. I am currently busy filing an I 539, which is the form for extending my stay. In order to stay I need to provide them with an affidavit that gives the reason for extension of the visa. Would it influence their decision negatively if they know that I'm extending my visa in order to apply for a green card? I would also like to know if there is a specific format for the affidavit?
I would appreciate any help.
