How long does it take for new immigrants to adapt to life?

The first stage: fresh period (about the first month. When I first arrive in a brand-new environment, I often think of myself as a tourist consciously or unconsciously. I am busy with sightseeing and shopping every day, and everything is so curious and fresh. Even if something is very different, it is not disgusting, but interesting. The new immigrants at this stage are very excited and in a good mood.

The second stage: the lost period (about the second or third month). After the sightseeing period, the novelty passed. See where you should see, eat what you should eat and buy what you should buy; It is better to see the scenery than to listen to it. Once something you've been longing for for for years arrives, that's it. At this stage, the sense of loss of new immigrants began to appear and their mood began to be low. The third stage: low tide (about the fourth to sixth month). If the cultural differences in the first two stages are not obvious, at this time, all the cultural differences in the new environment of new immigrants are naked, which intensifies the feeling that new immigrants are not used to, not pleasing to the eye and not adapted. New immigrants return to real life from tourists' fantasy: finding a house, finding a job, finding a school for their children and so on. It's annoying that everyone catches our eye.
