S.3235: A bill to reduce the amount of financial assistance provided to the Government of Mexico in response to the illegal border crossings from Mexico into the United States, which serve to dissipate the political discontent with the higher unemployment rate within Mexico.

Directs the Secretary of State to: (1) annually estimate the number of illegal border crossings along the southern U.S. land border; and (2) reduce financial assistance to the government of Mexico by a total of $1,000 for each illegal border crossing from Mexico to the United States during the previous fiscal year.

Authorizes the Secretary to not reduce appropriations for the government of Mexico from the International Military Education and Training Fund, the International Narcotics Control and Law Enforcement Fund, and the fund to carry out nonproliferation, anti-terrorism, demining, and related programs and activities.
