Federal immigration agents have begun stepped-up enforcement in Chicago, making the nation’s third-largest city the latest focal point in the Trump administration’s efforts to deport undocumented immigrants. 

The details are few, but the endeavor — known as “Operation Midway Blitz” — is a part of President Donald Trump’s dispute with Democratic mayors and “sanctuary cities.” The cities that have been targeted by the administration limit the degree to which local law enforcement must collaborate with federal immigration authorities. An executive order declared Chicago a haven for migrants in 1985.

On Monday, the U.S. Supreme Court lifted restrictions on Los Angeles-area stops related to immigration, allowing what advocates say amounts to racial profiling of communities of color.

Advocates said the deployment of agents and the court decision have put migrant communities on high alert.

Community and political leaders in Los Angeles and Chicago have urged caution to residents as law enforcement presence grows, while also denouncing the administration’s actions.

On Chicago’s West Side on Sunday, the Rev. Marshall Hatch told his congregation at a prominent Black church to “start telling people about your whereabouts, so you don’t disappear.” Hatch, who leads New Mount Pilgrim Missionary Baptist, added, “We’re not going to despair. We’re not going to feel threatened. We’re not going to give up and give in to fascism and authoritarianism.”

And in a Monday statement, Los Angeles Mayor Karen Bass condemned the Supreme Court’s decision. “The highest court in the country ruled that the White House and masked federal agents can racially profile Angelenos with no due process, snatch them off the street with no evidence or warrant, and take them away with no explanation,” she said.

As the administration’s deportation efforts continue, immigrants are encouraged to know their rights. This resource list was compiled using information from the Florida Immigrant Coalition, the American Civil Liberties Union, and the National Immigration Law Center.

If you’re a migrant or live with one, plan ahead

• Develop an emergency plan with your family. Memorize what to do, where to go, and whom to call or see if a family member is detained or deported.

• Gather key identity documents not needed daily — passports, birth certificates, immunization and school records, transcripts, educational certificates, diplomas and degrees, baptismal certificates and records, tax returns — and store them in a single, secure place known only to trusted family members.

• Carry a card or paper at all times with your loved ones’ phone numbers and names so that you may contact them even if separated from your cellphone. Memorize at least two reliable adult family members’ numbers. 

General advice when in contact with ICE or U.S. Customs and Border Protection

• Remain as calm as possible and say as little as possible. 

• Under the Fifth Amendment of the U.S. Constitution, you have a right to remain silent and not incriminate yourself. But, anything you say can be used against you in legal proceedings. And in some states, you must provide your name.

• Don’t answer any other questions. Instead, request a lawyer.

If ICE comes to your home

• Don’t immediately open the door. 

• You have the right to see a warrant. Ask the officer to slip the warrant underneath the door or display it through a window. If you open the door and allow the official to come into the house, this may be considered “consent” to enter.

• The warrant must be signed by a state or federal judge or a magistrate, giving the officer permission to enter your home. You’re required to open the door only if the warrant has your correct information, a valid date, and is signed by a judge or magistrate. Look closely. Sometimes immigration officers only have paperwork they have issued.

If ICE comes to your job

• Stay as calm as possible.

• Don’t run. Running may be considered an admission that you have something to hide.

• Don’t answer any questions, including where you were born, your immigration status, and your immigration or criminal history. Instead, ask to speak with a lawyer. Say aloud, “I don’t consent to a search.” This includes your property, bags, and pockets.

If ICE, CBP, or police stop you while driving

• If asked to do so, show the official your license, registration, and proof of insurance. Don’t show the official any false documents. Tell the official if you need to reach into a purse, pocket, or glove compartment to retrieve these items. Don’t answer any questions related to your immigration status or your birthplace.

• You have the legal right to remain silent. If you want to do so, say, “I want to exercise my right to remain silent. I want to speak with a lawyer.”

• If the officer asks to search your vehicle, you have the right to refuse. If you don’t want to give permission for a search. Say, “I don’t consent to any search.” If you say this, in some cases the officer can’t search your vehicle without a search warrant. If the official has what’s known as reasonable suspicion of a crime, they can search the vehicle on the spot without a warrant.

If you’re detained or arrested by ICE, CBP, or police

• Find out which agency has detained or arrested you. (What police department? Or are the officers with the FBI, ICE, or CBP? Ask.) Then ask for and write down the individual agent’s identification number and license plate number, if possible.

• In some states, you must provide officers with your name. But don’t answer further questions. Instead, tell the officials that you want a lawyer and will remain silent. 

• Contact a lawyer and your consulate as soon as possible.
