Under the 30-60-90 day rule, a person who applies for a change of visa status (including adjustment of status) within 30 days of entering the U.S. is presumed to have acted in bad faith. In other words, the USCIS will presume that such a person had preconceived intent to make the change before entering the U.S. and used an easier visa to avoid the normal screening process conducted by U.S. consulates abroad.
If the adjustment of status application is made between 30 to 60 days of entering the U.S., there is no presumption made. However, there will be a strong suspicion that the person acted in bad faith and heightened scrutiny shall apply.
If the adjustment of status application is made after 60 days of entering the U.S., the presumption will be that the person acted in good faith. However, previous visa history will nevertheless be examined to determine whether any abuses of the immigration process may have occurred in the past.
Looking at this rule you lie between 30-60 days period, so you can either be granted permenant residency or denied depending and how strong your case is.
this is what i would do.. i am not a lawyer but if you really want to stay with your wife and not go back here is the deal, but act accordingly..
If your wife is from the Indian Decent , I mean to ask if her parents are Indian, if yes you can prove this marriage to be an arranged marriage, USCIS knows that arranged marriages are common in south east asians and middle eastern people so you can make it sound like it was arranged after you entered america , and things were undecided when you first entered as a visitor, this is your best shot, But ofcourse its safer to go back and do consular processing , but this takes time.. good luck
