Hello, I am an Indian national currently working in China for last 08 years. I am married to a Chinese national since the past 04 years while completing all legal marriage formalities in China ( as per government rules & regulations) & registering our marriage at the Indian High commission. i do wish to get her to India for her stay with me & my family ( for the rest of our married life) for which i would like to apply for her residence visa in India ( or at the Indian High commission in Shanghai). Would it be possible to obtain an Indian residence visa for my spouse ? if yes, would it acceptable basis our marriage registration documents approved/ endorsed by the Indian high commission in Shanghai ? Would there be any pre-requisite terms & conditions with regards to culture/ religion (applicable Hindu law ), other than the Chinese marriage registration documents or any any other legal formalities (in china or India) that requires to be fulfilled to obtain Indian residence visa (long term) We have not completed any marriage formalities in India as off date, however we intend to do, if required upon. Sole objective for her to obtain Indian residential visa her to stay in India with me and my family as longest time possible without hassles of returning back to her parent country (China) for renewing short term visa.
