Once you have the application received, they have mentioned the instruction on how to re-apply if sufficient evidence is not met. They might be looking for some more documents on RFE, it might not be final rejection. So, get the documents first. If you can not get the documents back, there is nothing you can do coz the application filing date for TPS has already been over on Dec 24, 2016.

Please do not mind, kahile kahi loov garda ke .....milcha bhanchaa ni. Lesson to be learnt for future sathi.
