The Trump administration has relaxed some rules for H-1B visas allowing visa holders to enter the US if they return to the same jobs they had before the visa ban.
The US Department of State advisory said dependents, or spouses and children, would also be allowed to travel with the visa holders.
"Travel by applicants seeking to resume ongoing employment in the United States in the same position with the same employer and visa classification," the state department advisory said.
The US has also allowed travel by technical specialists, senior-level managers and other workers who hold H-1B visas, saying it is necessary to facilitate the "immediate and continued economic recovery of the United States".
President Donald Trump had signed a proclamation on June 22 banning the entry of certain non-immigrants with H-1B and L1 visas until the end of the year to protect the US labour market following record unemployment rates because of the Covid19 pandemic.
The US tech industry, including Facebook, Microsoft and Apple, had backed a lawsuit against the move.
America has also allowed the travel of visa holders working as public health or healthcare professionals, or researchers as the country battles the raging pandemic.
"Travel supported by a request from a US government agency or entity to meet critical US foreign policy objectives or to satisfy treaty or contractual obligations. This would include individuals, identified by the Department of Defense or another US government agency, performing research, providing IT support/services, or engaging other similar projects essential to a US government agency," the advisory stated.
