It is possible that your working license has expired recently, or it has been some time that you have been roaming around with an expired license. It is quite normal for people to go through this suffering. It is considered suffering because you know the time it takes to do everything all over again. The worst part is not paying the fee it takes to have it renewed but the long procedure. You know that you have done it all before and thoroughly, but now you have to go through the tedious process again. However, this free time maybe your a good time to renew EMA license.
Is it important?
Yes, it is important to have a renewed license if you wish to continue working. If you go to work or even take up new work or job with an expired license, you may be fined/penalized against the rules. You have to be eligible to earn in this particular field of work to prove that you have studied for it. To continue working, having a renewed license is an eligibility criterion. It would help if you found a way to have it done easily and in the least possible time.
