One of the main reasons for TPS application to go on pending is if u r missing with some info on ur application or u got wrong info or sent to wrong address(if sent by mail)which most of the applicants do then ur application gets delayed or will be pushed back until others who got right is cleared n then they will call u or send u email asking all the information u r missing with.So my best advice is to go on ur online portal n submit the written note u think u r missing with or u got wrong if u dont want to resubmit ur application with the fee again.i was missing with some of the imp. info on my applocation but i wrote a note n submitted n got approved now after a year submittion on Nov 20,2023.
