• States must apply, and be approved for, the financial assistance.

States are starting to take action around an extra $300 weekly unemployment benefit being offered by the federal government. 

But, as is the case with most aspects of the nation's unemployment system, details will vary by state.

Kentucky and Montana, for example, are giving $400 instead of the prevailing $300. Some states expect weeks to go by before workers receive the assistance, while Arizona started paying it last week.

The speed with which the payments arrive will partly depend on when — or even if — states apply with the federal government to offer the "lost wages" assistance. Then, their application must be approved. 

The more than 28 million people collecting unemployment benefits are likely wondering: What is my state's status? 

Here's a map of where things stand.

The Federal Emergency Management Agency, which is overseeing program funding, had approved 26 states to offer the extra unemployment benefits as of around 10:30 a.m. ET on Monday. 

Those states are: Alabama, Alaska, Arizona, California, Colorado, Georgia, Idaho, Indiana, Iowa, Kentucky, Louisiana, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Montana, New Mexico, New York, North Carolina, Oklahoma, Rhode Island, Tennessee, Texas, Utah and Vermont.

Officials in around 10 other states have applied or signaled they plan to apply for the assistance. 

South Dakota has said it will not apply for the subsidy. 

States approved for aid are guaranteed just three weeks of funding, with payments backdated to the week ended Aug. 1. However, they may get more aid, depending on how many states apply and how quickly the money is drawn down. 

Not all unemployed workers are eligible for the payments. Those currently getting less than $100 a week in unemployment benefits won't receive the assistance — amounting to thousands of people, and perhaps more than 1 million.
