@Tod ********
thanks for your input. Appreciate your advice. Maybe the solution is to get her dependent/ family visa here on the US passport since it has entry stamps and the following year, renew it on her Swiss. But I was told that only ChangWattana main office issues such visas, not the satellite ones : true ? Right now we don't want to travel to BKK.will wait to go when safer.Life is more important than paying an eventual fine. I found Imm to be very humane, when daughter' mom s was very pregnant and after cesarean birth, they allowed her not to do a border run, due to her condition with a medical certificate. Thanks folks
