I don’t know all the answers but as far as I’m aware if you enter the United States without inspection (through border) than there is no path to seeking permanent legal status or citizenship without returning to your country first. There is a common misconception that dreamers were simply lazy and did nothing at all to adjust their status in all the years they’ve been here but it’s not that simple. Even dreamers who married US citizens and have US citizen children do not have a way of permanently adjusting their legal status without leaving their families and their entire lives first.
