I have gathered information that Ada H16R10 works for 2 months and then go back for 1 month and so on. This means she doesn't get the work pass for her to work 6 months. It also means it will be harder to find her.
Then, after my sessions, I chanced upon the aunty OKT of H10. We exchanged pleasantries and afterwards inquired about Katty H10R10. She confirmed to me that Katty has resigned. She no more working! I still cannot believe it, but all good things must also come to an end.
Cheers.
