I have been in U.S.A. as a refugee since June 2010, also I have green card. Originally I am from Iran (Persia).
Can I have Import/Export company or business outside of US except Iran?
You can certainly open an Import/Export company. Your company can trade with all countries that are not officially boycotted (the most notable are Iran, North Korea, and Cuba, but other countries might have restrictions as well).
(a) You made a typo in the card number, CCV code, expiration date, name or address;
(b) Your card balance is too low;
(c) Issuing bank has declined this transaction for some other reason related to your account.
