Tex. Finance Code § 122.0131

If a state contiguous to this state experiences an emergency, on a request by that state's credit union regulatory agency, the commissioner may authorize one or more credit unions located in that state to open temporary offices in this state to more promptly restore credit union services to their members. The commissioner shall issue an order permitting the temporary office and specifying the period the office may remain open. On a finding that the conditions requiring the temporary office continue to exist, the commissioner may extend the period the office may remain open. A credit union may convert a temporary office authorized under this section to a permanent location and operate as a foreign credit union if it qualifies to do business in this state as a foreign credit union under Section 122.013 and commission rules.
