The United States has announced that it will close its only immigration office in Russia next month over what it called a “significant decrease in workload.”

The move follows two years of mutual diplomatic staff cuts and consulate closures after the U.S. said that Russia interfered in its presidential election in 2016. Late last year, the U.S. doubled fees for Russians seeking multiple-entry three-year visas in 2019, saying it mirrors the fee Russia charges U.S. citizens for a similar type of visa.
