The correct term is Pro Hac Vice. The original poster had some delusional idea they could be a lawyer without passing the bar, I believe they were not a Distance Learning Grad but a non ABA law school grad whose Kentucky law school went under without getting accreditation leaving them unable to take the bar in any state.
The only limited license I know of is typically between neighboring states. You can apply to practice in a state you are not licensed in on a case by case basis. Oddly, many neighboring states don't have reciprocity and an attorney may have cross over responsibilities. Hence the need for a limited license.
Of course, you must pass a bar in your own state and cannot abuse it. All this tax and immigration stuff referenced isn't relevant. Its a bar licensing thing, not a specialty thing. It can also be granted to a law student to practice under supervision, typically at DA or PD offices.
You should be taught this in law school, not trying to be arrogant or rude, but shi.t people this is day one. Do online schools not teach this? That's kind of scary.
