Pramila Jayapal's H.R. 1384 proposes a 2 year transition period:
Personnel will need to be hired and and systems will need to be developed during the first year following enactment.
After the one year anniversary of the passage of the legislation, eligible people will be able to "buy-in" to the program.
After the two year anniversary of the passage of the legislation, coverage will be available to everyone who is eligible under the program.
