2。 You can also consider Australian skilled immigrants, provided that you are under 30 years old and have at least 4 IELTS scores of 6! If you have passed your 30th birthday, you will get a score of 7 in four IELTS courses (of course, the alternative is to check whether you are married or not, and your spouse's education and English level can be determined).
3。 Skilled immigrants from New Zealand are not recommended, because without the guarantee of New Zealand employers, it is difficult to guarantee that your score will pass. Unless you like New Zealand very much and are willing to try it.
4。 It will be more difficult for other European countries, even if they have an employer's guarantee, they may not be able to get their identity.
