I've been living in India since 2010 and complying with the requirement to leave the country once every 180 days for years. I go to Nepal, spend the night and return to Dharamsala where I live. I just made this trip and was denied reentry, without any explanation on 9/27/2018. The immigration agent would only say that he is acting on orders from the Foreigner Registration Office in Delhi. I'm in Kathmandu, I've been to both the US and Indian embassies to make inquiries. The Consul at the US embassy said that he did not know of any official changes but said that he has recently heard of others like me (people who live in India on 10 year tourist visas) being denied reentry. Otherwise both embassies were entirely unhelpful.
My life is there, everything of value that I own is there, and two dogs as well.
Please don't respond with comments or answers that berate me for 'gaming' the tourist visa - India has been allowing this for decades, I know many people who've been here on tourist visas for way longer than me. Otherwise, I'm in compliance with my visa requirements. If they want me to leave because they've decided not to tolerate this use of tourist visas then they ought to at least allow me to get back to India to reclaim my possessions and put my affairs in order.
What I'm looking for are useful suggestions about how to resolve this situation.
