The Biden administration asked Congress on Friday to approve $6.4bn (£4.8bn) in aid for Ukraine.
According to US officials, the request includes $2.9bn in humanitarian, economic and security assistance for Ukraine and its neighbours.
The money would be released on an emergency basis through the US Department of State and the US Agency for International Development (USAID), a federal agency.
The funding request also calls for $3.5bn to help the US Department of Defense respond to the crisis.
Bloomberg reports the aid could be rolled into a large government spending package that is currently being considered by Congress.
The new funding is expected to supplement money the US has already committed to Ukraine over the past year.
Those measures have included $650m in security aid, $52m in humanitarian aid and a $1bn sovereign loan guarantee.
