1). Is my caste certificate issued by the Rajasthan Govt on my father's name is valid?
The community certificate issued by the competent authority is very much valid, because it is not obtained after playing fraud on the government or the authority.
2). As I was born in Uttar Pradesh and post my marriage my residence is Rajasthan now (home
state of my husband). Will I be considered as permanent resident of Rajasthan or just a Migrant.(please specify that if women married in another state considered as a migrant )
They cannot be considered as migrant but a bonafide resident
3). In the Central Govt SC Format (enclosed herewith), there is a point (point no 2) which is "to
be filled by the migrants only", do I need to fill that point while a wife is also considered as
permanent resident of her husband's state?
Your matrimonial home is your permanent house for life since you are married, therefore you may ignore the migrant column
4). Can I be issued the domicile of Rajasthan (Home state of my husband)?
You are domiciled in Rajasthan
5). I can avail the state reservation Quota of which state Uttar Pradesh or Rajasthan?
Since you are domiciled in Rajasthan and a bonafide resident of Rajasthan, you can claim benefits from Rajasthan also.
