If you have already sent in your return without him as a dependent, you can always do an amendment to correct for this and, it would be best to wait until you receive your refund to do an amendment on your return to prevent delays. Remember, you have three years to amend a return so you can wait for your refund before doing the corrections.
If you have not yet sent off your return, it would be best to wait for his amendment to be processed. If his amendment is not completed by the end of March I would suggest you contact the IRS
customer service line at 1 800 829 1040, for updates so you can process yours before the deadline.
