Quick answer
Form 8802 processing and Form 6166 issuance timing are controlled by the IRS and can depend on applicant facts, user fees, completeness, and IRS review. Tax Paperwork does not submit, monitor, expedite, or receive Form 6166.
Source and advice boundary
This page is education-only and not tax, legal, accounting, filing, payment, mailing, faxing, upload, confirmation, or representation advice. IRS.gov and current official instructions control Form 8802 mechanics.
What to check next
Verify current IRS timing guidance before foreign tax deadlines, keep payment and submission proof together, and use professional help when treaty, residency, or urgent withholding questions are involved.
Tax Paperwork can help organize public-preview draft context for some narrow workflows, but the user remains responsible for official-source review, professional advice when needed, and customer-controlled submission records.
Common risk
The common mistake is treating a draft, checklist, payment receipt, upload receipt, mailing receipt, or third-party summary as IRS confirmation. Keep records, but verify official channel rules and follow-up through IRS.gov, official correspondence, or qualified professional help.
