My wife is a belge citizen & we had applied for Long stay D VISA from India in july 2017 , just before 6 month completed I had received a mail from embassy that my visa is refused because my wife 1 year job contract is over . She did not get the new job as she is pregnant. Please suggest what i can do to get visa & meet my wife in belgium as embassy letter say i can appeal against the decision within 30 days.
