The status "PENDING FIRST DECISION" typically means that your revised paper is either:

Common Timeframe:

The first decision after a revision often takes anywhere from a few days to 2–4 weeks, depending on:

• The journal’s review and editorial process,
• Whether new reviews are needed,
• The editor’s workload and responsiveness,
• Whether the journal is experiencing delays.

What You Can Do:

If it has only been 1 week, this is still within a normal timeframe. However, if the status remains unchanged after 2–3 weeks, you can:

• Politely email the editorial office or handling editor,
• Ask for a brief update on the status of your revised manuscript.
