221g for H4 on dropbox

Hi, I applied H4 for my kid (below 14 yrs ) on Dec 8th through dropbox at Bangalore and now the status has chnaged to “Ready for Pickup”, i went to collect the passport, It was 221g, asking only me to come for interview… what would be the reason… ? Will there be an impact on my existing stamped passport??

They may want to ask you a couple of questions in person. Nothing to worry about. Please have all relevant documents of you (marriage documents),your husband (job, pay, tax documents) , and other documents that you carried with you for the first interview.
