One doesn't need to pay for a guide. The information is free and open to everyone.
I did some research a year ago (checked with every board of every state).
After completing residency other than AEGD/GPR you may apply for a license in the below states:
MN, MI, LA, MS, OR, TX, IL( IL is a very unusual state in terms of getting a license. They'll give you one after finishing 2 years of any residency.). Also, if you are OK with being restricted to working as a faculty, then count VA in, too.
After completing AEGD/GPR:
MN, MI, LA, MS, OR, IL, WI (1 year of GPR/AEGD is sufficient for this state), OH, KY, FL, VA(1 year is enough).
There are a couple states left unmentioned, like CT (residency-> limited faculty license for 3 years. Only afterwards you'll get an unrestricted license). MA (no residency required. Limited license. Community centers. Residency will give nothing). MD (license is given for a year only for pedo, GPR\AEGD). TN (limited license. community centers. Any residency is a requirement).
CA- 3 years of practicing as a specialist in any other state and you are eligible (reciprocity)
WA used to give a license after a 2-year residency. But heard the gateway had been closed.
By the time you graduate this information most probably will become obsolete (less states will be giving a license)
