My brother started a new job but quit after just one week. He only received payment for one day of work. Now, a month later, his former manager sent him this message:”Hello, good afternoon, Your file was left unfinished in the company could you go to the restaurant to make a copy of your passport and your social security as soon as possible please!! Thank you so much”We're not sure if he should comply with this request or if it's normal. Any advice or insights?
