my parents are travelling for the first time to Texas. with everything going around, is there any affordable health insurance plan for visitors or any affordable clinics around Dallas area just in case if they need it? they both are under 60 so Medicaid wont apply to them. any information on this will be very helpful.

Long time ago someone had posted about a health clinic opened by Nepali in Dallas.
May be this one.
