TS,
Let skip the r/s part between you and her for the time being ...
I suggest you go visit the ICA department personally to go find out for yourself why is the application is rejected.
- She might has violated some regulation in sillypore
- She might be caught for doing FL or whatever
Nevertheless it is so easy for the ICA department to send you a "unsucessful" application that they do not need to face any audit then a "sucessful" one.
Unless you push hard enough
