You must first be divorced from your current spouse. It is important that you make sure the divorce is finalized not simply filed before marrying your fiancé. You may marry your fiancé while she is in the United States for a visit, but she would need to return to Brazil for visa processing. A person cannot enter the United States on a tourist visa with the intent to marry and remain here permanently. This is material misrepresentation and can trigger a permanent bar to admission.
