Need Help with USCIS status Update

[oracle]

Hi

I have applied my first H1b in April but due to some reasons its rejected. and now i have filed motion to reopen (MTR), i got the new reciept number for this one.
When i am checking the old Receipt number status now its Says "your Alien Registration Number was changed relating to your I129, PETITION FOR A NONIMMIGRANT WORKER"

can some please help me to understand the status message

Can you elaborate the reason for H1B Rejection?

Dont worry USCIS changes Alien registration number pretty frequently and without providing a reason, and without it having any effect on pending petitions. Kindly schedule an infopass appointment if you need detailed info.
