The email you're referring to was sent by Upwork. Let us know if you have any questions about it or feel free to follow up directly on it. I also merged your post in the announcement thread where you can find more information about this.
At this time you cannot request to be invited. For the best chance of being invited in the future, we suggest freelancers achieve a solid reputation, keep a complete and up-to-date profile that is not set to private, and maintain an active Upwork account in good standing. You can find more information here.
Thanks for announcing this valuable information. I am a content writer and also have passion for learning designing. Is such an opprtunity available there? Would you like to provide me more details?
There are definitely a lot of opportunities on the platform for freelancers who have the skills and experience that are in demand among clients. Please, note that in order to be able to bid on jobs, have contracts with clients, build up their reputation and potentially earn Upwork Skill Certification, a user will need to have a freelancer account. Here is more information on how to create one. I'd also like to encourage you to check your private messages here and feel free to reply if you have any questions.
I got the invitation during the first week of October. I submitted the application and I didn't get any other follow up emails after that. Could you please let me know what is the status of my certification?
