So I will be going to korea eventually for plastic surgery to do facial contour, rhinoplasty and breast augmentation at one clinic. I’m from u.s. so I would have dollar bills. But I was wondering how is carrying cash through the airport and tsa.? Has anyone brought like up to 9.5k cash through airport without being questioned or is it better to just pay by card even though the clinic say it will be a more expensive with the vat 10%
