Yes, it doesn't affect it.
I think the answer is "yes". There is nothing in US law makes it illegal. However, with exceptions for military and diplomatic personnel, generally, US citizens permanently residing outside the US are unable to vote in US elections*. But not all nations are this way, and some nations allow, and indeed make special provisions (such as ballot boxes at consulates) to enable voting by overseas citizens. * If you are temporarily travelling outside the US at the time of the election you can usually arrange for an absentee ballot, but if you have no permanent US residence it is difficult.
Not legally. You must be a US citizen in order to vote in a federal election. However, there are many reports of people who are not US citizens voting illegally.
i don't think so
YES.
No
The US recognizes dual citizenship.
Yes, you can apply for German citizenship and be a dual citizen regardless of the fact if your mother was still a German citizen or not.
she have to marry again in israeli
I think that if your father was (and/or still is) a US citizen, then you are also a US citizen no matter where you were born. It should be rather easy to get an american passport in the US embassy or consulate in the phillipines for you. As for your mother, I believe that she has to apply for a US visa or "green card" based on her marriage to your father who was/is a US citizen, or thru your US citizenship if you are over 21 years old.
No, you can live abroad indefinitely and still maintain your American citizenship.
By law, the US doesn't recognize dual citizenship (i.e. constitution prevents dual nationality) but somehow it always does recognize it.
No. The US president MUST have US citizenship only.
Yes dual citizenship is allowed for US citizens.
No he still lives in the UK. If he does live in the us he has dual citizenship between the us and UK
Yes.
Spain does not have dual citizenship agreement with the US.
If you apply for citizenship in another country your US citizenship is automatically revoked. The US does not recognize dual citizenship. You revoke it in writing at a US embassy, outside the US.
