Some countries will accept only a recent Single Status Affidavit which has been issued in the past one to three months. In China, you may only do one Single Status Affidavit every 6 months, and the affidavit is valid for half a year from the date the consulate authenticates it. The affidavit must be submitted to the Chinese consulate for authentication within 90 days after it was apostilled. We recommend that you contact us to check with the country requirements on how old the Single Status Affidavit can be.
