Hello.
If you are a US citizen you can apply to adjust his status in the US since he entered legally.
There may be a problem regarding his domestic violence conviction.
If it rises to the level of a crime of violence then his adjustment will be denied and he will be placed in removal proceedings.
The DUI will not bar him from adjusting status.
Please contact my office to provide me specific information about his domestic violence charge. I offer free consultations.
