All of this is just something to disturb the ignorant.
What is required on the application? (There are supplementary forms depending on your answers to the basic form and I have included some of the questions.)
Date and place of birth Date and place of birth of parents Citizenship, naturalization, etc. data. Length of stay at other places you have lived (For Obama this would include Jakarta, Honolulu, etc. in addition to birthplace. For McCain it would include U. S. Canal Zone, etc.) Name, address, email address, former addresses Former names or aliases Immediate Travel plans Names of two guarantors who will vouch for you Social Security Number (Social Insurance Number in Canada). Date and last place of income tax filing
All of these data are easy to get through investigation services and credit data concerns.
The Social Security Number is on your tax returns, your mortgage contract and loan data, your banker's data, stock brokers data, etc., etc., etc. Easy to find by one in the finance or banking business.
