The story about Canadians in France and Russians at the conference (https://www.anekdot.ru/id/1194367/) reminded. A friend of mine from Russia accepted an invitation in the late 1990s to work as a researcher at a Canadian university. He liked his work and life in Canada, and six months after his arrival he filed for the PMJ, soon receiving it. His career at the university settled: a year or two later he received a professor's position, excellent funding, results above the world level, publications, invitations to conferences with reports, contracts with leading firms... At some point, the man began to stress the need for frequent visa filing against the background of the Yugoslav War and the other eleventh of September, and he decided to get a Canadian passport: it was easier to travel around the world and in general... The census of settlement (the owner of the PMJ there needs to live a bit on the territory of the country in order to be able to apply for citizenship) he almost lacked, some ammunition-three months, but he didn't want to wait, he used a point allowing to include prices in foreign business trips, and brought all his trips there at conferences, which were in total He formed the documents, sent back, in response - silence. Finally, after almost the same three months that the friend asked to be counted in the census, comes a paper: an immigration judge (there are some there) calls him for an interview and demands to bring proof of the facts of holding all the declared conferences at the given time in the given places (copies of the programs of the conferences), as well as proof of the applicant's active participation in them (copies of published works of these conferences with theses and articles under the authority of our hero). My friend cut off everything necessary, pulled a thick folder with him. The old judge looked at it all carefully, then asked him to explain what his friend was doing, and then said about the following: "I feel deeply guilty to you. The fact is that I myself in my youth was a professor at the university and I know how popular "conference trips" to resort locations are at the expense of the state. And when I saw that you had enough courage to call business trips “conference trips” to San Francisco, Honolulu, Cancun, Kyoto, Nice and the like, I decided to teach you a lesson: to draw the answer of those 3 months that you demanded to count, and finally to arrange a conclusion for trying to present entertaining trips as business. I didn’t believe you could actually work hard there. But now I see: you are a world-class talent, and also a worker, and I was deeply wrong in giving you a sentence in advance, and the only way to smooth my guilt is to give you citizenship right now. Repeat my oath.”
