If he created it on Zalera, which is still a preferred world right now, he won't be able to transfer the character until 90 days have passed. It's in place to encourage less populated servers to fill up and remain filled, since transfers to preferred worlds are free from congested worlds.

Since it sounds like he just started playing, I'd recommend he just create a new character on Lamia; he'll miss out on the Road to 60 buff, but that mostly means he won't be overleveling the MSQ and/or need to level multiple jobs at once.
