My wife was in H4 and she applied for H1 visa through some consultant on April'09. The consultant applied H1 visa and Change of Status from H4 to H1. But my wife had to go back to India due to some personal emergency. She will be coming back on August'09 in H4 visa. Her H1 is still not approved.So, now I am not sure what will happen,

1. If her H1 gets approved then will Change of status be approved as well? If change of status is also approved then will She moved to H1 status as of 1st Oct?
2. How would she know that her Change of Status application (from H4 to H1B) is approved by USCIS?
3. What will happen if She don’t get any project through her consultant? Will she be out of status?

Please advice me about this situation.
