No. If you are looking to sponsor someone applying from overseas, you will need to complete that process on your own. Though we do allow employees from other countries to sign up and apply for jobs on our site, we do not participate in the hiring process. This means that any actions or paperwork in connection with sponsorship would need to be worked out between you and the potential employee.
We do, however, recommend checking out your government websites regarding sponsorship as they will be able to provide you with all the necessary information on how to proceed.
