I've been issued only a single-entry X-visa valid for 1-year for studying at BLCU starting Sept 2010. I asked for multiple entry but the embassy lady told me that they can't issue that. If I want to go travel somewhere for the X'mas holidays, I can simply go to a "local police station" to have it amended there (and I'm sure that I didn't confuse this with the temporary residence permit which is completely different). Can you confirm if this is correct?
