Is it normal for my visa application to stay in 'pending document check' status for 20 days?

Yes 20 days in pending document check is normal now. Many embassies have many DTV applications so they take time. Sometimes it stays on that status for two or three weeks then changes fast to approved. So your case is normal.

Congrats on approval, that heart shows you are happy. Now print your DTV approval email and keep it with your passport. Also save a photo on your phone. At the airport they may ask to see it. First entry they may ask about your work and bank so keep those papers ready too.

If you want tips for first entry after approval and what to do next, there is a good step by step part in Unlock Thailand by Isla Rey on Amazon, it explains what happens after pending and how to enter smooth. Enjoy your trip to Thailand.

Yes, it’s normal, just be patient

Mine said that for 10 weeks lol

I applied the 1st of September, 28th days later they asked for more documents, the 1st of October it changed to pending aproval, and still waiting since then...

Those “status-messages” does not tell or predict anything of meaning to the applicant.

Every embassy is different read the Embassy website of the Embassy you applied at.

Only workdays count, and a request for additional documents reset the count to 0 on the day documents ar submitted.

May I know which country are you applying?

Back log currently if that helps. 15 working days is the target if your not an emergency last minute application is what I know. It has been suggested that some have waited over a month.

Probably wouldn't hurt to send them an email, or a message. I think i had to. I forget what was holding mine up.

In most embassies: yes
