Myself and my wife are Indian passport holders and both my children are American passport holders
Day 1 - land in SG (by SQ)
Day 2 - depart for Bali SQ
Day 7 - Arrive in Singapore from Bali SQ
Day 9 - depart to USA from Singapore by SQ
1. Are there any visa or transit requirements for US passport holders?
2. Since I will be entering Singapore twice in my itinerary, will I be eligible for vftf? My total stay in Singapore both ways combined is less than 72 hours
