While filling out form I130 in part 4 I filled in the beneficiary's passport number for both Q47 (passport number) and Q48(Travel Document number). I thought this was suitable as I interpreted q48 to be the document my spouse used while travelling to the US on an ESTA. After reading certain topics regarding this topic on the forums I have come to see it is an entirely different document and N/A would have been probably more suitable of an answer for Q48. My case is yet to be approved or denied. Should this pose much of a concern? Should I wait for a decision to be made and possible RFE? Or is this unlikely to affect anything?
