well u cant straight away apply for indian cpl after that but u can apply for indian rtr and get an indian rtr and then apply for indian cpl
however there is a provision that if ur recency is expiring and u have applied for indian rtr but u havent got one then u can apply for indian cpl but then u will have to give a cover letter stating that ur indian rtr is still under process
in that case dgca will accept ur application but wont issue ur cpl until u give them ur indian rtr
