In the US one has to be accredited investor to buy stock in a private company.
However, does one still need to be accredited investor in case a public company goes private (i.e. get delisted from stock exchange) to retain already purchased shares?

No, they cannot force you to sell simply because of your status. When companies go private though, they frequently invoke "drag along" clauses in shareholder agreements which may specify that in the event of such a sale, everyone must sell.
First, being delisted is not the same thing as going private. If a stock is delisted from its exchange, it can still trade publicly "over the counter" or on the "pink sheets", and you do not need to be accredited to hold such shares.
As TripeHound commented, "going private" normally requires buying all outstanding shares, and this can be done because a majority or supermajority vote of the shareholders can force everyone to sell. If not all shares are bought, that would be "acquiring a stake" rather than "going private", and the remaining shares would continue to trade publicly.
Once you own publicly traded shares, there is no normal process that would leave you owning non-publicly-traded shares.

That's not correct. The private company is only allowed to solicit investment from accredited investors. Non accredited investors are not barred from investing in companies and many many many many non-accredited folks are invested in other people's small businesses.
