I don’t mind answering it here just so that anyone else who may have a similar issue can benefit some day from this thread..
I asked the question in this forum on a separate thread just before I filed, if I had to fill just one form with two biometrics fee for my 19 year old and the response was yes..
I also read in the Uscis website, the instructions read.. that I had to include any children who got green cards within 90 days… and so, his and mines have the same timeline and expiry date as well..
Honestly I didn’t see an age limit, unless I missed something. But, from other responses I saw that others were getting through with kids his age and older.
Im hoping that this was just an honest mistake on their part and that they correct it or if any mistake on my part then I will be able to correct it…
If not, then I will write them and try again..
