I work in Nigeria, and now my boss won't pay me, and my work visa has been deducted by my boss. Excuse me, how to return to China? Can I go to the immigration office and say I lost my visa?

If you work hard, why doesn't the boss pay you? All conditions must be settled before going abroad. The boss cheated you, how to face other employees? Find the reason from yourself first. And if you really meet a "dirty" boss, the only solution is to go to the China Embassy. The visa fee and air ticket for going abroad are more than 10 thousand RMB. Your boss won't let you leave without saying anything!
