You will need to obtain your sister’s information eventually - take the time to get all of the requested information now.
You will need to go back through your eQip to look for the blanks. Sadly, the eQip validation just means the program accepts your submission. Additional information will probably be needed after the submission is reviewed. Also - you will probably have to talk to an agent/investigator if information you provide (such as your sister’s naturalization number) doesn’t match the information in the various databases.
Taking the time to thoroughly and correctly fill out that form will save you a snot load of time during the investigation.
Try to obtain the information as requested and if you can’t get it because it doesn’t exist or she won’t give it to you…explain that fully in the optional comments section. Be very careful about entering false or dummy information into the equip. It doesn’t look good without an explanation.
If you list the wrong number the person with the wrong number will be flagged as undocumented. If you list the correct number you may not need a face to face interview but if you list the wrong number it will trigger a face to face and that’s when you can provide the correct number.
why in the world would you list relatives not needed to be listed? The only time you list bro-in-law, nephews and nieces are when they are foreign nationals.-Then you list them under foreign assocations.
