Does Illinois eligibility expire?

Should say something on her letter, any reason why she has delayed it so long. There usually is some date of expiry but can differ from BON to BON

All letters of eligibility have an expiration time to them. She needs to read what is in the letter sent to her or contact the BON.

there is no written expiration for IL eligibility so she can register to pearson whenever your friend is ready to take the NCLEX.

BUT, you have to remember also that the whole application to IL is valid only for 3 years.

Conditions of Application--Applicants have three years from the date of the Department's receipt of the application to complete the application process including passage of examination. If the process has not been completed in three years, the application shall be denied, the fee forfeited, and the applicant must reapply and meet the requirements in effect at the time of application.

hope that clears everything!

It is written someplace for every single BON, you just have to look for it.
Same way that no nursing license does not have an expiration date on it.

Three years is not the norm for any other state.
