There is no such thing as a national massage license. There are national massage and federal massage tests, but the names are deceiving because you are not nationally or federally licensed just because you take those tests nor are those test givers accepted by all states.
Every state requires something different. If you are licensed here in Texas and move somewhere else requirements may be different and your Texas license may not be accepted. I know of LMT's have come from Florida, California, New York who have trained and practiced for years but have to do the 500 hour schooling all over again here in Texas to get a Texas License.
If you practice without a license in Texas you can be fined big time. If your fined enough times you get jail time.
You cannot advertise body rubs or sensual body rubs or any like statement without an actual massage license period. One caveat however, is that giving a foot massage / foot reflexology alone is not considered massage therapy, so we are seeing a lot of asian foot spa's pop up all over the place where none of the people working in those establishments have massage licenses.
You cannot practice in the nude or partially nude if you do have a license.

Other interesting facts:
The job of licensing and inspecting (Spa's, Salons, individual therapists) falls to Texas
Department of State Health Services, but the state relies heavily on local police to enforce the regulations. There is just one full-time state investigator assigned to routine inspections of licensed businesses. Five investigators, shared with other state programs, review and investigate complaints against licensees.
Christine Mann (Texas department spokesperson) said the massage licensing program could be eliminated as part of a series of proposed budget cuts, though any decision to do so would be made by the
Texas Legislature.
"One of those options is to eliminate the massage therapy licensing program in Texas worth $1.5 million over the 2012-2013 biennium,"
