My son had many expenses on his internship of two months, he is a full time student and I support him. He is 22 yrs. old.   He must have spent at least $2,000.00 of his earned money on hotels, car rentals and only received $650. on his return. Is there a reason for this? the accountant said that it was because it was not enough money he made on the whole year and left it at that. Could you confirm for me.
