Thanks for your prompt reply. Sorry I would like to ask a bit more:1. Your current passport.
2. Only the one for which you have the ECA.
Since I've been using "Passport A" frequently during the past 5 years, and I never use "Passport B". However, I would like to use passport B for the EE profile. If I receive ITA, I will be asked to enter all my travel history.
1. Will that be a problem if my passport B is empty?
2. Do I have to provide passport A detail after getting ITA to prove my travel history?
Thanks a lot!
