Explanation:

• The Jammu and Kashmir Reorganisation (Adaptation of State Laws) Order, 2020 substitute the clause for ‘permanent resident of the State’ under the Jammu and Kashmir Civil Services (Decentralisation and Recruitment) Act, 2010, by ‘Domicile’ of the Union Territory. Hence, statement 1st is incorrect.
• Before these orders, only permanent residents of J&K were eligible to apply for the gazetted and non-gazetted posts but now non-domiciles can also apply for these posts. Hence, statement 2nd is correct.
• Someone who is registered as a migrant by the Relief and Rehabilitation Commissioner (Migrants) will fall into the criteria for being a domicile. Hence, statement 3rd is incorrect.
