What I learned from the reading and the film is that if you want to become a citizen of that country, you must live there or work there for many years, but there still has some exception like if your couple came from that country, you could become a citizen for that country immediately. For example, if you want to become a US citizen, you need to live in the us for 5 years or more, but if you got married to a US citizen for over 3 years, you could still become a US citizen. But for some countries, you can never become a citizen of that country. For example, China is not accepting any foreigner to become a Chinese citizen, no matter how long they live there, they can only get to live in China but not as a citizen.
Citizenship means to me is you become a part of the country, you will feel very comfortable to live there, you will also feel a sense of belonging. People who born in us or becoming US citizens are considering a part of the US. They belong to this country because they build a family and having friends and jobs in this country.
