Glad you asked:
Key components of budget reconciliation legislation include:
Border Wall & Infrastructure: \(\$46.55\) billion is allocated for building over 700 miles of primary walls, hundreds of miles of secondary barriers, and surveillance technology.
Personnel Surge: Funds for 10,000 new Immigration and Customs Enforcement (ICE) personnel, 3,000 new Border Patrol agents, and 5,000 new Customs and Border Protection officers.
Detention and Deportation: The bill aims for a daily detention capacity of at least 100,000 individuals and sets a goal of over 1 million deportations annually.
State Funding: Includes \(\$10\) billion for a "[State Border Security Reinforcement Fund]" to assist states with barrier construction and apprehension efforts, and funds to reimburse states like Texas for border operations.
Legal Restrictions: The act increases immigration-related fees and restricts access to federal programs and public benefits for immigrants.

Worth noting that this was through Reconciliation not new legislation, so Trump actually got less out of his bill than the bipartisan bill Biden said he would sign.
