Countries usually do not like to extradite, especially when the victims are not the state but other individuals. Most countries do not extradite a person convicted under 1, 2, 3 years. Depending on the country, you cannot be extradited from Switzerland for a sentence under 2 years, I believe. The USA and Canada, I believe, do not extradite for sentences under 5 years. I know cases when a person forced 15 employees to take out bank loans in their name, for themselves, and then moved from Romania to the Netherlands. The victims sent photos from Facebook and showed pictures including the school where their daughter went in the Netherlands. They were never extradited to Romania.
generally, countries have extradition agreements that establish the conditions under which individuals can be extradited. Typically, a country will not extradite someone for minor offenses or short sentences. It is possible that certain countries have different rules regarding extradition based on the length of the sentence. It is important to check the specific laws for each country to confirm the details.
