COS - H4 to F1 in Student Visas Posted January 3 · Report reply Thank you for your inputs. I had a lil bit of hope on this Senator's letter, but your opened our eyes to the reality. A helpless father out here, trying all that he can to keep the family knit together. Actually, our second son is blind and has a lot of mental challenges and both of them get together very well. We migrated to this country only for him. I explained this situation to our senator and thought this could help us, if the senator was kind enough to let the CO know of our situation. Thank you, once again, not just for this advise to us, but on behalf of all the user who post in this forum. Very much appreciated, Sir.
