My boyfriend is in jail for dwi, two of them, will he be deportes after doing his sentence,and can we get married while hes in jail and start his pape

Your boyfriend stands a good chance of being placed in removal proceedings. DWI/DUI is taken very seriously and this is his second conviction. You could marry. You may be able to start the process to obtain lawful permanent residence for him but more information is needed. I would need to know about his manner of entry and any other criminal history to determine how to best proceed.
