The Employment Authorization Document (EAD), which is more popular as work permit, is an ID that shows that you have been allowed to work in the United States legally. EAD is given to those immigrants who get the right to work in the US along with their visas.
Many people wonder as to what makes the EAD different from Green Card. Green Card is provided to people who get permanent resident status in the US. And you can work in the US either you have an EAD or Green Card. But what makes these two documents different is the fact that if you have Green Card, you have permanent status in the US. What this means is that your right to legally work in the US does not carry an expiry date. On the other hand, the EAD comes with an expiry date, meaning that you can work on an EAD for a limited period. The EAD or visa will carry the expiry date.
Green Cards do come with an expiry date, but when your card expires, it does not mean that your right to work in the US has ended. The expiration of the Green Card does not affect your permanent resident status, whereas that of the EAD ends your right to work in the US. If you decide to extend your visa, you would be required to renew your EAD if you want to continue to work in the US.
The time covered by the EAD is determined on the basis of the duration of your visa. Ideally, you should apply for renewal of your EAD in case your EAD and visa are soon to expire. And the good news is that the applicant is not required to get a sponsor for an EAD. Your visa already authorizes you to work in the US. The EAD is merely proof that you are allowed to work.
