Thank you for your reply. I understand that nothing excuses his law-breaking. But is there any way that he could be approved for change of status ? His whole immigration situation is so confusing. He entered the US under a Q-1 visa, and after leaving the work he had the visa under, he applied for a tourist visa, renewed it right before it expired, and later went for a student visa so he could go to school, but was denied. Would it even be possible for him to get a green card after getting the change of status with all this ?
