Hello aspirant

hope you are doing well and safe. With reference to your query,  I would glad inform you that validity of ews certificate is of one finanical year which is valid from 1 april of current year to 31st march of next year . For valid certificate of 2022 ,you have to reapply and that will be issued after 1st april 2021 and valid till 31st march 2022 . You just apply for ews certificate any how and you to go with whole process as renewal facility is not available in ews certificate

Hope you found this answer informative. Best wishes for your future
