To find a white girl friend is much more difficult than to find a job.
(Ironically, same difficult to find a Chinese girl friend if you are not
rich enough because they are more pragmatical)
To fit in whites, you need to have very good English and very good
understanding of western culture. They are not so snobbish as Chinese
girls. But it is difficult for us to cause their consideration, because
we have little in common with respect to cultural background with them.
For job you only need to have some relevant professional
skills, which is not a big deal compared with the former.
Any way, it is worth trying if you have opportunity. But
do not expect too much on that. Especially for marriage.
