First, always beware of passports sold ‘under the counter’, too-good-to-be-true offers, quick fixes, proposals to sell you lists of countries/programs/grants, connections in the government, other schemes that will rip you off and put you in trouble with the law.  Second, if you are interested in obtaining citizenship based on exceptional economic or other merits, as is the case in Austria, you should be sure that the relevant regulations are stipulated in the laws of the host country.
