To dream of the immigration department may reflect feelings about needing permission to make a significant change. It may also reflect feelings of needing to stay out of trouble or prove yourself in order to maintain your increased level of freedom. Feeling that if you don't show enough respect you will lose your status or privileges.
Dreaming of being stopped or questioned by the Immigration Department may represent fear of being cut off from something you have recently started to enjoy. It may also reflect a fear of being forced to return to a less pleasant or lucky life situation.
