My mother is an Indian citizen, and will become a US citizen in December. After that, she wishes to marry her boyfriend, a citizen and resident of India, and bring him to the US. My mother is 67 years old, and retired. She would be fine living in India for a few months to a year to expedite this process through DCF, and we have the finances to sponsor her boyfriend. In these circumstances, is it best to use a K-1, K-3, or DCF process?
