I am just concerned that after sponsor call, if information is requested, is this a sign that my application is being considered positively Or PO could decide on the basis of information available with him. TIA
Like Said you did never know the nature of the ADR until you get an email to that effect. To receive a sponsor call is a very positive sign your application was considered positively as sponsor verification is the last among the many evaluations. Information could be requested if the PO officer is unsatisfied with an answer by the sponsor or an information was discussed that has no documented proof. Rejection after sponsor is so rare, therefore do not fret, it is just a verification process nothing serious.
