The short answer is: Yes! You are eligible for jobs on Nomad. The chief requirement to be qualified to work jobs posted on Nomad is an active medical license.
However, we will say that most facilities that use Nomad for locums are looking for doctors who have completed residency. That shouldn't deter you from applying to jobs though. If you are looking for a permanent position for when you have completed residency, Nomad would be happy to help you -- feel free to register here.
Finally, if you're having trouble completing Nomad registration, just put your internship year as your residency and that should get you unstuck. And of course, let us know if you're having any other issues -- we are happy to help.
