I am an international student in the US, and I’m going through a background check before I start my job here. During my final year of undergrad, I worked as a freelance web developer for a small marketing firm in my country. As proof of self employment, I sent my background check company (First Advantage) the contract I signed with my client and bank statements showing their payment to me, since that’s all I had at the time.

However, they rejected those documents (even though they said a bank statement should work), and are asking me to submit a company registration. I don’t have one since I was not registered as a company, just working as a student. I called my client and they said they can give me a letter stating that I worked with them in a freelance capacity, and I can create back-dated invoices for the payment they made to me.

What are my options at this point? I can’t figure out what I can provide them that will help them verify my employment.
