Venezuela will limit the number of US diplomats working in the country, President Nicolas Maduro has announced.
Nicolas Maduro said he wanted a review and reduction of American diplomatic staff.
American citizens visiting Venezuela would also need visas and there would be a list of politicians who would be banned from entry.
Nicolas Maduro said US meddling had forced him to adopt the new measures.
The president said that the US government had 100 employees working in Venezuela whereas Venezuela had 17 based in the US.
A list of banned politicians would include George W. Bush, Dick Cheney, Bob Menendez and Marco Rubio.
Nicolas Maduro said these were all men who had violated human rights and encouraged terrorism, particularly in Iraq and Syria.
Earlier this month the US imposed visa restrictions on unnamed Venezuelan officials it accused of human rights violations and corruption.
The move builds on sanctions imposed last year on Venezuelan officials alleged to have violated the rights of protesters during demonstrations that shook the country in the first six months of 2014.
The list of officials banned from entering the US was extended to include family members.
Earlier this month President Nicolas Maduro accused the US of working with opposition groups to stage what he said was a coup that involved bombing the presidential palace.
Washington rejected the accusations as ludicrous.
Venezuela and the US have not exchanged ambassadors for the last five years.
