I have very funny question which is not related to PN or any health condition. Please - don't laugh....

We are on a process of getting American citizenship to our children (as my husband is US citizen). We don't live in the states - but we need information about my husband and about his parents (also american citizens).
Here in Israel - we have identity card and identity number (which, since the age of 18 - we must carry all the time). What is the parallel in the states? is it the SSN? How can I asked for information? such as - periods of staying in the states, work places ect.

I told you - funny question....

looking forwards to hearing from you

thanks
