US Secretary of State Marco Rubio on Saturday said Washington’s new green card policy is part of a broader global immigration overhaul and is “not about India”, according to an interview with NDTV during his India visit.“Well, it's not about India. It's about the whole world,” Rubio told NDTV when asked about the new US immigration policy that requires many legal immigrants already living in the United States to leave the country and apply for permanent residency from abroad.Rubio said the United States decided to reform its immigration system after facing what he described as a major migration crisis.Also Read: Want a green card?

The fact of the matter is, and I think every country would understand it, again, this is not about India. This is a global situation that we're dealing with,” he told NDTV.“Our country, unfortunately, faced a very serious migratory crisis a few years ago. Over 20 million people unlawfully entered the country. We saw abuses of the green card system in many cases as well. And so we decided that we were going to reform it,” Rubio said.He acknowledged that the transition could create short-term difficulties for applicants.Also Read: Marco Rubio unveils ‘America First’ visa plan in India for business travel“Any time you reform a system, there's going to be some disruptions. There's going to be some hiccups. There's going to be some inconvenience,” Rubio told NDTV.The policy, issued by the US Citizenship and Immigration Services (USCIS), says adjustment of status applications for green cards inside the US are discretionary and should not replace regular consular processing abroad.The move could affect temporary visa holders, including students, researchers, tourists and H-1B workers, many of whom rely on adjustment of status provisions while living and working in the US.Indian technology professionals have historically depended on the process because of long green card backlogs and country-specific visa caps.Rubio, however, said the new system would become more stable and efficient over time.“Much more viable. And I think Indians who seek to come to the United States are going to find themselves with a system that, in the long run, is going to prove to be more efficient and more effective and better for both them and our country as well,” he said.Rubio arrived in India earlier on Saturday and held talks with Prime Minister Narendra Modi on trade, defence, energy and Indo-Pacific cooperation. During the visit, Rubio also conveyed an invitation from US President Donald Trump for Modi to visit the White House.Earlier in the day, Rubio also announced a new “America First” visa schedule focused on business travellers while speaking at the US Embassy Support Annex Building dedication ceremony in Delhi.
