All I can comment is based on the information I’ve got through the applicants who submitted the application recently
I think with BLS there is always a sense of uncertainty.....whenever you go to them take the entire set of docs you have whether they ask or not...and if they ask, please give....
while they are streamlining the process, my experience says that their website says something..and in reality their officers do something else....
Dont understand some of their actions....for eg....why should the checklist print out be beyond the first page....thats the actual document check list....rest all are just instructions....when i had gone for my application some had only their first page and did not have the rest....they were asked to avail the print out services and print the rest of the docs...
Website says professional letter.....but when i took it....they gave it back to me saying it is not important and it is needed only if you are in military....but then why put it as a requirement....
I gave them the complete set of docs of my oci application (7 pages), they took only the application page - which is the first 2 pagesand rest 5 are instructions - which were returned.
Marriage certificate....birth certificate are other artifacts which are again not clear.....
so be prepared to take print out of everything ...and the once they retun ...trash it.....wastage of money for print outs / printer ink and paper.....
