When I file the I-130 petition, I know I need to show both original passports, as well as copies of the biographic pages. Will my Chinese wife's original passport be retained at that time, or will it be returned to her? I will need it to apply for an ITIN for her later. Also, can anybody explain what this means: " Your wife needs to apply for ITIN with IRS. If she needs her Chinese passport to be certified, please make an online appointment with ACS for notary service." What is meant by a "certified" Chinese passport? Is the original passport in some way "certified" or authenticated, or is a certified/authenticated copy issued? Or must a "certified" copy of a Chinese passport be obtained from the Chinese Government?
