Many many thanks for you prompt reply. Some clarifications for your information please.
During my studies in the US (late 1980's), my son was born in the US. We as family went back to India after my graduation as part of a contract and hence had to raise our son in India.
We are law abiding folks coming from educated and well cultured families having many friends and relatives who are well settled professionals in the US for decades. We understand the importance of the US security and investigations and associated delays which are part of the process. We look upon US with awe and respect and hope things work out well.
