Key Info About San Ysidro Border Arrests
Which Agency is in Charge of Border Crossings in San Ysidro?
US Customs and Border Protection (CBP), a part of the Department of Homeland Security, manages border crossings in the US. The agents of CBP can and do arrest people suspected of violating federal laws while entering the US at a border crossing.
US Border Patrol, which is part of CBP, is responsible for patrolling the border between official ports of entry. Border Patrol agents focus on border security and arrest people caught crossing the border illegally – those who don’t use official ports of entry to come into the US.
Immigration and Customs Enforcement (ICE) is responsible for immigration enforcement within the US, but not at the border. ICE is also part of the Department of Homeland Security, but it is separate from CBP and the US Border Patrol.
What Should You Do if You’re Arrested at the Border?
US citizens who are arrested at a border crossing can take certain steps to protect themselves.
San Diego border arrest attorney Russell S. Babcock suggests declining to provide any information besides name, address, and telephone number, as well as declining to sign any waivers or otherwise voluntarily submit to a search of a vehicle, phone, or your own body. Babcock also recommends not revealing the specific cause of arrest when making the allowed phone call to a loved one or attorney.
Instead, it’s crucial to ask the officer or agent if you are being arrested and to get the name of the facility where you will be taken. When you are allowed your phone call, provide this information to your contact and, if you speak to a family member or friend, ask them to find a lawyer who has experience with laws related to federal border crossings.
How to Find Someone Detained at the Border?
Finding a friend or loved one detained at the border can be a difficult process. US citizens involved in a San Ysidro border arrest will generally be taken to a nearby federal jail and have their case heard at the San Diego federal courthouse.
Your best course of action in these cases is to contact a lawyer experienced in federal border laws and arrests. When your loved one receives their phone call, it’s crucial to ask them which facility they will be taken, if they don’t tell you.
If you need to find someone detained for an immigration-related reason, the National Immigration Law Center offers a detailed guide to finding a friend or loved one in this situation.
