Hello Sir, I'm currently in H1B Visa and my 6 yr visa MAX Out date is end of July 2019. My husband is in F1-OPT Visa. Can i apply for change of status from H1B --> F2 dependent visa on May 2019? If I apply petition for status change on May 2019, remaining 2 months of my H1B visa will be valid in the later time to apply for H1B extension with approved I1140?(I haven't started my I1140 yet. Planning to start after a break at end of this year). Please advise whether my change of status would work ? and my remaining H1B visa time can be used for further extension in later point of time?
