Sorry I didn't get a chance to be online sooner..
Thank you Johnjoe20 & Waves for your replies.
My husband's office is at Barkly Wharf East, Le Caudan Waterfront. Unfortunately he doesn't work on flexible hours. But in Jakarta, we also commute around 20 km everyday to go to work & school.. also in a very crowded traffic.
My husband had visited Alexandra House and fell in love the minute he arrived there. It's actually what we're looking for. But like Waves said, the waiting list is sooo long. We put our daughters' names but not very optimistic.
I guess we can only wait now. I try my best not to be stressed out thinking about the school (although honestly, it's just sooo hard not to think about it
Anyway.. yesterday I have submitted my (and my girls') visa application and I'm so excited. My husband took lots of pictures and said that the country is a great place to say and the people are very nice & helpful. I can't wait to be there..
Once again, thank you all for your replies!
