Hard to add anything to the comments of Ken Jones, ASA, SCGREA, CRES! He has it covered. 

Yes, if he/she is licensed in those states. I know many agents that work 2-3 states, especially in DC.

Are you and the broker both licensed in both states?

  First question:   Probably.  But I would see a real estate attorney, and/or check with the Real Estate Commission in each state that is involved in the story.

  Follow up question:  if he isn't licensed in the state, then he cannot legally do business in the state (at least here in Florida).  So, no.

Yes, if the broker has the needed licenses.

If I'm reading this correctly, you are asking if Broker Bob is a Broker in Alaska and Nevada can you hang both your Nevada and Alaska licenses with him?  I believe so, but have never investigated.  It may be that they have a different company name for each state.

Robert Vegas Bob Swetz works in those two states from my example and may be able to better answer the question.

As to the follow-up, your broker must be licensed in that state for him to do business.

I hope you got the right answer from all of them. Good luck. 

Great question and asnwers. Good luck. 

If you can answer yes to Bob Crane 's question.

You have many great answers here Quinn Eliason 

Ken Jones, ASA, SCGREA, CRES nailed this one!

Quinn Eliason - I think the answer should be 'YES' - however, check the guidelines with the board of each state.

Quinn, I'm a broker in two states and I have agents who are under my license in both states. I'm not sure what operating means if you are not performing real estate transactions. Even finding a rental for someone is a real estate transaction. In that case, you need to be affiliated with a broker in that state. 

Being in the center of Colorado, only licensed in one state.

one broker PER state. 

You must be licensed in the same state(s) as your broker in order to work in those states.

If you are licensed in California but not Nevada and your broker is licensed in both states, you would not be able to work in Nevada unless you obtained a Nevada license.

If the principal Broker is also licensed in the other state, yes.

1 broker in each state.

Second question is No. First yes.

I know a few agents who are licensed in different states but I never ask them in details about their arrangement with their broker.  

Not something I have faced. Yet. Good question. 

Ken has answered 

I wish you all the best with your real estate studies. 

Quinn Eliason Yes, as long as both you and the broker are licensed in these States. If you do not do real estate transactions you do no have to be licensed. I don't see the point to this though unless you are doing non-related licensing activities.

Quinn,

You have the answer.  A

Yes, however, whatever states that principal broker is licensed you must be licensed there also.

It depends on state laws and how the broker/brokerage is licensed. I am licensed in NC and SC and hang my licenese with one brokerage.

You have the answer from the others.

Both you and the broker need to be licensed in those states, he as the broker and you as an agent. So the answer to the first question is yes, subject to licensing; to the second, no. You can be affiliated with a different broker in another state if that broker has a local broker license and you have a local agent license.

Yes sir, at least in the States where I have my brokers license in

Yes, sure.
