各國入籍條件比較？

Well, what you think is not always what you get, you need to understand, if you think there aremore freedom or more opportunties overthere, you should think again......

新加坡，美國，加拿大，澳洲，德國，英國等國的移民入籍條件比較？

It is really not hard to neutralise to become Citizens of one of the country, it is getting residence that's hard.

The difficulty of getting citizenship from the easiest to the hardest should be

澳洲 -> 加拿大 -> 新加坡 -> 美國 -> 英國 -> 德國

Let me explain what you need to get Citizenship, in points form

Australia

- 4 Years Legal Residence
- Citizenship exam

Canada

-3 Years Legal Residence
-Citizenship exam
-Citizenship Interview

Singapore
-2 years Legal Permanent Residence
-Must either be employed or married to Singaporean national
-Do not allow dual citizenship

USA

-3 years (Marriage/Asylum), 5 years (Other) Legal Permanent Residence
- Citizenship exam
- Citizenship interview

UK

- 7 years legal residence (At least 5 of them as permanent resident)
- Citizenship exam

Germany

- 7 years Legal Residence (5 for EU member)
- Citizenship Exam
- German Language Exam
- Not allow dual nationality

Notice that you cannot become a national of other nation's overnight. There are some rule you need to obey generally, such as as good health and as good character.

As i said before, getting citizenship is not hard, getting Permanent Residence on those place are way harder than you think

加拿大國籍可以自由進出美國而且要移民加國比移去美國容易得多
