I have got H1B petition approved this year. I have received form I797. The petition validity dates shown in this form are from 10/01/2016 to 06/15/2019. So my query is how long can I extend to apply for the process of Visa Stamping and If I extend are there any consequences occurring.
Also If I apply for visa stamping and then I get the visa then will its validity time will be same as that mentioned in I797. Also please suggest me which way is better to extend. Should I apply late for stamping itself or go for stamping , get the visa and then wait till the time I want. Thanks.
