Hi,
 
	As my passport (A) expires next year, and given the IR1 visa will be a 10 years period, I have applied for a new passport (B) to coincide with the 10 years duration.
 
	All forms submissions were based on Passport A. I am going for my interview with US Embassy in Singapore in July 2024.
 
	 
 
	My questions:
 
	1. Which passport details (A or B) should I enter into the ustraveldocs.com? 
 
	2. I thought the ustraveldocs.com is to indicate my choice of passport delivery. Somehow, I've seen appointment schedule tab, that shows nothing was scheduled. Can this be ignored?
 
	3. Do I have to inform the US Embassy of my new passport details prior to my interview?
 
	 
 
	Many thanks
 
	Hana
