I don't see how it is a good idea, no matter the circumstance, to upload a copy of personal identity documents, such as driver license or passport, especially in return for the potential of earning a few hundred dollars.
Trying to see why UPWORK needs a copy of my license...
Tried applying to a job. Says it wasn't saved after I submitted it, stating it was required that I was a US citizen, and needed me to upload a phot of my license.
The message disappeared but it passed me to this screen:
I turned off my ad blocker ad converted the pdf (license) to jpg file and it still didn't work.
I asked Upwork for help through these threads, but, I am waiting for a response.
