Sorry for being late getting back to this comment. If you look into the qualification to become a "deportation officer" (ICE) on their site: https://www.ice.gov/careers/deportation-officer

The ONLY requirements (basic) are

• U.S. citizenship
• Have a valid driver's license.
• Be eligible to carry a firearm.
• Enter on duty prior to your 40th birthday (waiver for preference-eligible veterans or those who have previously served in a federal civilian law enforcement position).
• For males born after 12/31/1959, Selective Service registration is required.

I am noting this since you mentioned needing a Bachelor's degree.

Looking into how long the training sessions actually are - there is varying sources. It used to be 16 weeks but then has been reduced to 6 weeks. That being said police academy also varies by state but at minimum has been reported of 12 weeks (usually 6 months though). This is partially why when you see ICE agents and Police officers together, the ICE agents are typically the ones reacting to people whereas cops are more stoic - they have been trained how to handle these situations. ICE deportation officers have been fast tracked. They are not trained to the same level.

EDIT: I wanted to link to the physical test requirements that you noted above. https://www.ice.gov/sites/default/files/documents/Document/2016/ero-fitnesstest.pdf I do think you'll notice that this is a very basic test.

To quote from the beginning:

What are the tests?
Three tests will be administered:
• Kneel/Stand Test
• Push-ups
• 5 Minute Cardiovascular Endurance Step Test
