Hello sajha,
If an army applicant is married and his wife is nepali citizen and currently lives in Nepal. While he is applying for a citizenship, can he also apply for his wife citizenship together? Or she has to go through petition to get green card first?

Greencard through consular processing

DV भर, DV परेर आयो भने सजिलो हुन्छ।

@tinagurung, के जे पायो त्यही सजेसन दीएको। जुन कुरा आफुलाई थाहा छैन चुपो लागेर बस्नुनी।
@Radha Timalsina, No your husband cannot apply you citizenship. He can only file a petition for you to get green card. After certain years when you are eligible for citizenship you have to apply yourself.

@Halfkattu you are correct.
