If you're interested in Tx, you probably need to know that we have LV
Ns, not LPNs - same in CA.
Many hospitals & LTACs still employ LVNs in bedside roles & they make up the majority of licensed staff in LTC. Nurse practice acts differ, so you probably need to carefully explore LVN scope of practice in TX - ours do a lot more than in many other states. You'll have much more luck outside the major cities.
In the meantime, go ahead and start the ball rolling to get your Tx licensure... this may take some time because of the lack of standardization in vocational/practical nursing programs
in the US. You may discover that there are some additional educational requirements that you have to undertake - such as the 'Jurisprudence' educational requirement that Tx grads are required to complete.
Best of luck. Please
make sure you have a job lined up before uprooting yourself for the move.
