I'm pretty sure steppybay will come in and reply with a very detailed and informative post.
Per this thread:http://allnurses.com/nurse-registrat...me-760249.html
, there are 13-15 states that have concurrency issues. And unfortunately, the list may be growing.
Also, note that New Mexico, the state formerly known as a "fast state," has implemented a new rule. See this thread: New Pinoy RN planning to apply New Mexico + take NCLEX. HELP please.
Just know that if you are planning to have a license in a "faster" and "easier" state and then try to endorse it to a CA license, that will not work. CA will still say you are ineligible due to your concurrency issue, regardless of whether or not you a licensed in a different state.
This thread has a discussion about taking the LVN/LPN boards: http://allnurses.com/nurse-registrat...ow-681582.html
Do your research. And good luck! Pick a state where you want to settle for the long-term, and not the short-term.
