Vishals: Can you post your checklist with each application you filed. That way, moderators can quickly identify which paper you have forgot to send. Also, I believe, you MUST have made photocopies of ALL the papers you sent to USCIS. See if you forgot to fill in any mandatory information or forgot to sign any paper. Finally check whether you sent in the payment from the bank that is still in the business.
Hope, you don't get any RFE. I love your pre-emptive strike but had you checked your check-list in prior, you could have saved some anxiety, water under the bridge. Never mind.
