Answer:
a. Current Account.
b. A credit to the Current Account.
Explanation:
When people go to another country for work and send the income they make back to their country of origin as remittances, this goes to the Current Account of a nation's Balance of Payments.
It would be recorded as a credit to this account because when money goes out, it goes to the credit side of the U.S. BOP as it is being exported out so is leaving the economy of the U.S.
