I was in BC last August 2011. I was returning to the same school for a second contract, but my trip home was during the summer vacation and before my contract expired in October. Of course being home, I did the paper work there where English is magic for getting things done. The RCMP told me that there are two types of Criminal Record Check one with a vulnerable sector search and the other without a criminal record check:
-The Domestic one which requires fingerprinting and a vulnerable sector search
-The other, for those working outside of Canada, does not require fingerprinting or a vulnerable sector search. The RCMP counter clerks (not RCMP themselves) assured me that one w/o the fp or vss was fine, but they're not going to stand beside me at Korean Immigration. Against all of their persuasion I opted for the costly route of having both done. The Domestic one took 2.5 weeks to be ready.
When at Korean Immigration in Yangu, the clerk asked me for fingerprints, and I showed him the domestic criminal record check containing a vulnerable sector search and fingerprint authentication. He took it, then asked me to do an electronic finger print check on the spot with a nearby electronic pad. However, I have read other's Korean Immigration stories wherein RCMP fingerprints were not requested, nor was the expat printed on the spot.
Note: on the form she will fill out at Korean Immigration there is a line that goes something like "Depending on the individual case, Korean Immigration reserves the right to ask for additional documents"
To be very certain of what's required you could:
1. call Korean Immigration at 1235. Their English is good, but they're a tad impatient.
2. visit your gf's immigration office with a coteacher or bilingual friend and ask specific questions. Better yet, write out a list of what he/she said and have them sign it.
3. suggest your girlfriend do both criminal record checks.
