The slip was issued to a Romanian passport holder, probably on the 31 December 2014 permitting the holder to stay for up to 30 days. The holder departed on the same day, 31 December 2014. Using same slip, the holder entered into Northern Cyprus again on 2 January 2015 and also departed on the same day.
Visa on arrival was issued when crossing from Southern Cyprus until May 2015.
Whilst it is completely unnecessary, as visa stamps for the TRNC in passports are not illegal in any other country, including Greece or south Cyprus, holder may prefer to not have his passport stamped on arrival and departure. In this case the may request for a separate visa entry form which is then stamped and needs to be kept for his departure when it will be stamped again.
If he intend to visit the south of the island during his stay, then again he will just need to produce either his existing visa paper if he did not want his passport stamped on arrival, or complete a new one at the checkpoint.
