Must the vowed money be disbursed in the same country where the vow was made, especially if the amount is not currently available?

If a time or place is not specified for a vow, there is no harm in fulfilling it at any time or place. However, if a time or place is specified for it, then it is obligatory to fulfill it according to them. Delaying it due to inability is not sinful, as long as there is no negligence.
