I will have 98 + 73 = 171 days left on the 6 year H1B period ending on April 14 2012.

Question
1. Can I file for H1B extension through recapture for 171 days starting on July 15th 2012

Quick summary of the facts
1. First H1B started on April 15 2006
2. 6th year of H1B expires on April 14 2012
3. 98 days of time spent in H1B that can be re-captured

5. No Green Card filed, no intent to file for one
