safe stamping duration...

[h1aspirant]

My current I797 approval notice is valid till Mar'07. My company has applied for renewal this month, but given current processing times, it may not be approved until jan-feb'07.

I have an appt in india for stamping in nov this year. My question is that whether I may have problems due to the near expiration of my old 797?

This is my first h1 stamping.
