I have a similar problem.
I have long registered for an upwork, yet under a maiden name.
but began to work actively only now, after the wedding, and change the name.
You need to fill in the tax form and connect payoneer. and they are already on a new surname.
what do i do (step by step)?
first change surname on upwork?
or I can first fill in a tax form, without changing the name on your site?
How to do it right so that I have no problems?
