H1b Stamping scheduled for this Tuesday but I have doubt

I have following doubts:

  1. I forgot to mention in DS-160 that few years back my B-1 was rejected at consulate

  2. After scheduling my Reciept number at uscis showing in ‘Initial Review’ because one of the document got undelivered

  3. Cash in hand in bank statement is very low

However, I have all the documents with which includes original I-797, LCA, employer tax returns, offer letter , I-129 etc. Also, I have been working for this company as a full time freelancer and my bank statements shows consistent montly payments (more than 20k $ in last 5 months).

What are my chances of getting the stamp.

Can please somebody share his experience in such situation. Very tensed.
