I am on H1B visa, my wife is on H4 Visa. My wife got H1B approved this year her petition start date is 01-October-2014(end date is 30-September-2017).
My wife H1B petition was approved on 18-April- 2014
I changed my H1B employer last month, got an approved petition on 17-August-2014 .I also applied for my wife H4 extension along with my H1B transfer & it got approved on 26-August -2014 .I was not aware of the last action rule that time so applied from wife H4 extension during August 2014.
Last Action rule will consider the petition approved date or petition effective date. Her H1B petition has the I94 with effective date as 01-October -2014 .What will be my wife Visa Status on 01-October-2014 which is her H1B petition effective start date?
