Remove a decade long backlog for Indian nationals coming to work in Skilled fields (STEM, Accounting, Healthcare, Finance, Law) by speeding up processing times by hiring more bodies at USCIS Processing Centers.
And also maybe not forcing every Chinese national who studied STEM in China to go through enhanced background checks [0].
And also hiring more immigration judges (I knew a former Immigration Judge with the DHS - they de facto had a hiring freeze since the 2010s, leading to case backlogs).
Tl;dr - stop defunding the DHS and USCIS
