Ok here is my situation. I am in the travel industry and am all over the USA Canada and Mexico. I have my Drivers License valid in Costa Rica, I have a state ID in Texas where my father lives. I stay in hotels the majority of the days and do consider CA my home state. My physician in TX is willing to fax all medical data needed or via phone call to qualify me to be a medical patient. Will I be forced to get a CA DMV ID? Being I stay in so many different cities I do not have a mailing address in CA. I am thinking I will have to get a POB in CA to have a CA ID mailed. How strick are the medical physicians if I do not have a state issued ID but can more than verify my medical condition via fax from my doctor in TX along with MRI data. I understand unlike Costa Rica you do not receive a CA ID the same day within the DMV office. Any suggestions on my situation would be great. Thanks in advance.
