The meaning of voice is to ask you to press 1 for English services and 2 for Chinese services, as this is a scam specifically targeting overseas Chinese. Then if you are Chinese, he will tell you that your visa will be revoked.

They definitely don't know who you are because I made up a fake name, but no one noticed. The meaning of voice is to ask you to press 1 for English services and 2 for Chinese services, as this is a scam specifically targeting overseas Chinese. (In fact, I tried to press one. When I got a call in Chinese, I asked him why he didn't speak English. I pressed one. Why didn't you speak English? Because I knew he was a fraud call, I was free.) Then if you were Chinese and you pressed Chinese, he would tell you that your visa would be revoked. Actually, upon careful consideration, what important thing are you worth having the immigration office call you personally?
