I always travel with two passports as it comes in handy when I enter the country of citizenship.
Though I`m curious of how US Immigration would look at it if I were checked out. Would they accept it as, no worries or would I be checked out because I`m so dangerous...

Just an innocent question.....what do you reckon?
Anybody experienced the full treatment due to this?

Using the passport of a country you are a citizen of when entering is not only "handy" -- it's generally required

It doesn't matter as long as US citizens enter the US using US passports. I've had DHS do a full search on me, and they found my other passport elsewhere in my bag. After 20-30 minutes of doing a background check, they told me everything was fine and handed both passports back to me.

Keep in mind that for US citizens to have protection abroad (such as embassy services like emergency airlift in the case of riots or government overthrows in the host country), you must enter that country with your US passport.

will not.

I have a UK and a US Passport. The US does not recognize the dual citizenship but the UK does. So I use my US passport to reenter the USA, but I use my UK passport everywhere else. It is much less trouble overseas than a US passport.

Never had a problem with this arrangement and I would never expect one.

I suppose the problem comes in when the names on the passports don't match, when discovered during a search -- that could be an interesting experience.

That said, I've toyed with the idea of getting an Irish passport. I qualify for dual citizenship and having a non-US passport on hand seems like a sound idea when entering the EU, and also if one finds himself in a situation where being an American is a bad idea.

But the issue that I've seen with two passports is the lack of ability to get a security clearance. I don't have the links handy, but I found references to a number of cases where security clearances were denied simply because the applicant possessed a non-US passport (IIRC, one instance was one of these Irish passport situations, so it's not like the person had a passport from a country that is often viewed as unfriendly to the US). In my job (consulting), I have had occasion to consult with government agencies, although a security clearance has not yet been required, I expect that I'll need one at some point.

As long as Israel exist will be no problem with two passport in US, but can be issue with a security clearence.

For people whose work requires frequent travel to both Israel and other Mid East countries, can they be issued two passports from their own country? I doubt the US will, but I've heard Germany will. Can anybody confirm this?

AA is right Germany does issue two passports -especially for the Isreal / middle east problem but also for those travellers who frequent the eastern european countries & Russia..... many require visas and the embass�es are not known for their speed so you might find your passport on the road for about 4 weeks on occasion. Some business travellers have to travel on the one passport while the other is being processed for the next route / travel arrangement.

I'm pretty sure the US will. I've seen references to the rules for second US passports here on FT.

The U.S. is notorious for failing to share dual citizenship; in all but very limited cases, you are supposed to renounce your non-U.S. citizenship in becoming a U.S. citizen. Many other countries don't require that at all.

My understanding (having gone through the whole clearance process) is that even if the citizenship is that of a closely allied country--say Canada, the U.K., or Japan--it will be seen as potentially undue foreign influence and may cause the clearance to be denied (and for higher level clearances, will definitely cause problems). It may not be a problem, for instance, with a Confidential or Secret clearance--for which the DSS or other agency will often forgive past criminal convictions, high current debt, etc.--but for Top Secret and various SCI clearances, that's a big no-no. The DSS required me to list any and all friends or family of foreign nationality, and for those who weren't yet in the process of obtaining US citizenship (one who was Chilean was holding out to try for dual status), I had to answer a ton of questions--as I did for a girlfriend from the PRC from many years ago. Oddly enough, my cousin's wife who was a Russian national garnered NO questions, since she's now a US citizen.

The general rule at my organization for foreign nationals is "ties of kinship, affection, or obligation." It's a pretty sucky position to be in if you have family or a spouse with non-US citizenship as you have to report it everytime you have contact with them.

For example, having college professors of different nationalities (surprisingly, one of which I think was Iraninan) and a Chilean woman I shared office space with in my previous job didn't need to be reported in my application as they didn't meet the criteria mentioned above.

However, it's real fun for a guy I work with whose sister-in-law just married a Venezuelan. He has to report it every time there's a family activity, etc.

That said, it shouldn't necessarily be a deal breaker for a high level clearance as the government does work very closely with organizations in other countries.
