My son completed MS in Indl.Engg. in 2012. He had applied for H1b in April 2014 and April 2015 from a consultancy company. Both were denied. He is now doing an on-line course till Jan 2017 with CPT with another consultancy. I intend to visit him in April 2016 for 4 months. I have a different relative who will sponsor my visit. I have sufficient property and income in India, and will bear the entire expenses myself. Will I have any difficulty in obtaining the visitor visa. Thank you.
