I went to a few posts and few articles on web and came to know that to apply resident visa for my new born i would required the following :
copy of passports (parents)
copy of resident cards
rent agreement
attested marriage certificate
copy showing visa stamp in passport (to prove visa validity)
attested birth certificate
company documents
salary certificate
but i am confused about medical certificate, does my new born require a medical test 'fit' certificate? does he is required to visit the lab? as the lab might increase chances of any kind of infection to the new born given my son is only 22 days old right now.
