This is a complex case, but one well worth review by an experienced immigration attorney with a practice focused on deportation defense. The bullets issue may not be a bar to adjustment, but review of the state statute under which he was charged is required, as is a review of the court records for the stolen property. As to aggravated felony, just because the Government says it's one, doesn't necessarily make it so! I would urge you to consult with an experienced immigration litigator as...
It depends on how you are seeking to adjust status: marriage, employment, etc. This could be a problem, but if in truth you never worked as an F1, at least if you were not in an OPT period, you may be able to adjust. I recommend you speak with an experienced immigration lawyer.
This means that a decision has been made on your case, and a decision letter mailed to you, which you should receive very soon. If you don't, then I would highly recommend you consult with an experienced immigration lawyer.
This depends on when you got your permanent residence, and if you were already married when you did, as your wife may be eligible for a permanent residence as well. I would urge you to consult with an experienced immigration attorney as soon as possible.
Although not necessarily a reason for USCIS to deny your case, it does raise a red flag because it begs the question of why a married couple would not trust each other to commingle their finances. You will need to have a valid excuse for this, as it simply seems that there is not enough trust in the marriage to commingle finances.
You should submit as much evidence as possible to show that you have had a true courtship, such as: pictures together, cards or gifts exchanged, letters and emails, evidence of telephone conversations, and evidence of trips taken by the US citizen abroad to meet and spend time with the foreign fiancée.
The I-90 is the correct form, and just wait another month before you renew the card. Also, if you have been an LPR (lawful permanent) resident for more than 5 years, you should maybe speak to a local immigration lawyer about becoming a U.S. Citizen.
That will depend on two things. First, is the marriage a real, true, and loving marriage, and not one just for immigration purposes. Second, does your J-1 visa require you to return to your country for two years (if so, there is a waiver for that requirement).
