I'm extending my visa through work tomorrow. That requires 4 x 6 cm. photo. After contact, I plan on re-entering with a SETV, getting a couple re-entry permits and travelling around for a 1-2 months before returning home. Also requires photos.
Various information says 4 x 6 cm. Also, I hear 3.5 x 4.5 cm. I would like to just go to the photo shop once and get photos for the rest of my time and be good. Would 4 x 6 cm or 3.5 x 4.5 cm work best for getting SETV and re-entry permits?
