Unlocking DS 260, may cause problems for my case and my visa interview? (interview time speaking - my cn is EU11xxx, andThe possibility of an unlock request depends on how high or low your CN is, when you make the unlock request and when you resubmit. If your CN isn't low enough as to become current in October, then I think it's okay to make the request.
particularly about the possibility to have a USA visa and a Green Card too). Thank you
