Flying from Russia with a connection in Rome. In Fiumicino, a border guard, rushing somewhere and already getting up from his seat to leave, almost without looking, stamped the entry stamp - as it turned out, on a Chinese visa. Having discovered it, I returned to ask if it was okay, but he was no longer there, there was another. The other took my passport, said there were no problems, checked the visa — or what they are checking there under some light — and stamped the second entry stamp on the same Chinese visa! When I told him that I already had one, he shrugged his hands and his stamp in the corner, where the circle of stars, crossed, and again said “no problem.” He has no problem, but I...? Now I worry about what this threatens me and what to do.
