Hello aspirant,

Hope you are doing great.

As per your question, Mostly the EWS certificate is valid for one year. Irrespective of the date which you have applied, the certificate is valid for one year. So after getting the certificate look at the year and the month it is given, basing upon that you will know the validity. Hence, wait until you get the certificate. If its not valid, then you can apply for the new one.

Hope this helps!
