For those states that do not provide guidance, I've linked to their general unemployment information sites:
Oklahoma has posted this statement on their unemployment website:
This gets us through 32 (plus DC) state links on unemployment administration. Click on your state to go directly to guidance or information about who is eligible for extended benefits and how to access them. If your state isn't listed here, click for Region I (New England), Region II (Mid-Atlantic) or Region III (Southeast).
Next up, Region V (Upper Midwest), followed by Region VI (Western).
