Hello, my name's Alaa I need an advice about proofing my experience actually I have 6 years of experience in my career but the problem is i worked at 3 companies without legal contracts or Social insurance and I was paied cash because the companies that I worked at don't have legal license, there are two companies of them can give me letters individually containing my title, my responsibilities, how long I worked with them, and how much I was paid and the both of letters will have the signature of my manager and all contacts of the companies ( contact numbers - emails - websit ) so is that enough or I can't proof that I have experience because I don't have legal contracts ( that's common in my country many companies work without legal license) ? Advise me please
