Can you tell me the process of buying a social security number in order to work in the US as an immigrant?

In order to buy a Social Security Number (SSN) as an immigrant in the US, you must fill out an SSN application online or by mail, and provide the necessary documents and fees. Once your application is approved, you will receive your SSN and be able to start working in the US.
