After September 17, 1978, no foreign bank may establish a branch, and after one year following such date no foreign bank may operate a branch, in any State in which the deposits of a bank organized and existing under the laws of that State would be required to be insured, unless the branch is an insured branch as defined in section 3(s) of the Federal Deposit Insurance Act [12 U.S.C. 1813(s)], or unless the branch will not thereafter accept deposits of less than an amount equal to the standard maximum deposit insurance amount, or unless the Federal Deposit Insurance Corporation determines by order or regulation that the branch is not engaged in domestic retail deposit activities requiring deposit insurance protection, taking account of the size and nature of depositors and deposit accounts.

Notwithstanding the previous paragraph, a branch of a foreign bank in operation on September 17, 1978, which has applied for Federal deposit insurance pursuant to section 5 of the Federal Deposit Insurance Act [12 U.S.C. 1815] by September 17, 1979, and has not had such application denied, may continue to accept domestic retail deposits until January 31, 1980.
