i plan to do KUL IKA but do not want to get permabanned from U.S.A.

is the passport the only hard record US embassy can refer to when checking for visits to naughty countries?

if so, will scheduling a trip to IKA on the last year of passport validity then applying for US visa on a new blank passport a reasonably good tactic to keep my trail hidden from prying eyes?

Just because your passport expires doesn't mean your history does.

Why would you want conceal it though? It only excludes you from the visa waiver program for 5 years but then, as you're saying, you were planning to apply for a US visa for some other reason anyway. A trip there shouldn't change anything in your situation.

Totally read this as "strategy to conceal visit to IKEA"

As this topic pertains to US passports/regulations/policies, we will move this to the USA forum for further discussion. Thanks. /JY1024, TravelBuzz co-moderator

so is there an official worldwide database that shows all movements of all citizens?

because i believe it is an unofficial ground for refusal of entry to u.s.a. which i also plan to visit, maybe when the climate is better.

haha good one, i dont think i have ever been in one.

A new passport won't necessarily make a difference, but sometimes it may make it much, much easier to not get hassled about an otherwise undisclosed prior trip.

There are ways to take a legal trip between some countries without it being all that easily tracked and utilized by a foreign government that isn't part of the trip in some way. Besides being concerned about what PNR tracking, passport control data sharing, stamps in passports, loyalty program activity, and online/internet activity may indicate, there is also some tracking that takes place via financial activity monitoring. Is it really worth it to undertake an action plan to do all that is possible to avoid having the trip noticed by a hostile government? I don't know, as that's an individual decision. Personally, I don't suggest visiting countries that are hostile to my travel interests.

Probably no official one, but if the US find out about it via one channel or another (e.g. Selfies taken in Teheran on your FB profile, a newspaper article about you visiting Iran, spy programs, etc...), you'll be in a lot of trouble.

Legally speaking, a new passport will not solve the problem (They aren't that stupid in congress ) and you'll be asked in your ESTA application if you travelled to Iran since 2011 and not if you traveled with your current passport to Iran.

Honestly I don't see the reason why you would want to hide your visit and potentially get into serious trouble. Visiting Iran is (currently) not prohibited. It only means that VWP eligible passengers will no longer be able to travel under the VWP to the US. These passengers will just need an ordinary visa, which isn't that hard to get for most people.

Conclusion: Travel to Iran. Apply for a US visa. Get your US visa. Travel to the US. End of story. It's certainly not worth it getting arrested, questioned and ultimately deported and banned for years. Trying to hide a trip to Iran is the kind of suspicious behavior, US immigration and anti-terror agencies don't like.
