My parents went for US - visitor visa from India. BOth of them are retired people. Father worked in Defense Research and developement Labs(DRDL) and mother worked as a lecturer. Visa officer just asked few questions like when they were retired and what was their proffession. My mother told that she is a govt. lecturer and retired and then visa officer did not ask any further questions. But in father's case, she asked what did he work on. He said he worked in DRDL and was into designing,he did not mention any further details,did not use the word missiles.His actual work was to design hardware components for missilles. Then they were given a 221 g form with following questions..and to send an e-mail with the documents attached. Description of your current or most recent research/professional projects in details and description of practical applications of your most recent research or study. Assume that you are describing your work to a technical expert, scientist, or professional in your field Description of your professional and academic background. Please attach a complete CV/resume and a complete list of publications and professional/research references. Please let us know what we are supposed to do. My concern is my father worked in design of misilles in india and if he says the same in the e-mail then it might lead to more queries. Also since he is retired, there is nothing to write in CV. and he does not have any publication of research papers. Please let me know how we should answer this query and how much time it might take to resolve this. Please help me in this issue as the visa is very much needed.. Currently both my husband and myself are on H1B US visa. In some cases,people are getting further queries even after submtting the documents requested for in 221(g). Is it true that the chances of getting visa are depends on the color(such as white,blue,pink,yellow) of 221(g) form that is given to the applicant.
