Im a US citizen that lives in chicago but i have my boyfriend that got deported 6 years ago to mexico im trying to bring him back what can i do

More information is needed about why he was deported to provide a thorough assessment. Assuming your boyfriend was deported solely for being in the United States without status, you will need to marry to be able to petition for him to receive an immigrant visa. Your boyfriend will need a waiver, because of the prior deportation as well as for unlawful presence. These waivers are required if someone tries to return less than ten years after removal. You will need to show you will suffer extreme hardship if he is not admitted to the United States. Under no circumstances should your boyfriend try to illegally re-enter the country as this will trigger a permanent bar to admission.
