When can the ICND2 be taken after passing the ICND1?

[Zake202]

I'm wondering if there is a limit on the amount of days a person can wait after passing the ICND1 before continuing on to take the ICND2? Or are they separate and the days between don't matter?

Also, does the state in which it is taken matter? I may be taking the ICND1 in MI and then the ICND2 in MN, but I could not find if the place taken mattered.

Thank you
