Initial import of configuration should immediately bring in IMAP folders (at least names)
When I imported a config file exported from K-9 into Thunderbird for Android only the Outbox folder was shown. After exploring some options in the gear menu (thus consuming a little time) the folder list still hadn't populated. I set the phone aside for a time and came back to it. The folders had been populated. I suspect that it may have waited the Folder Poll Frequency time period (15 minutes in this case) but I don't know this for a fact. Initial setup should retrieve the folder names immediately. This will provide feedback that the setup/import was successful.

Hey Dennis, Thunderbird for Android is still in Beta. The developers are ironing out some issues here and there. If you need more assistance, feel free to ask at https://support.mozilla.org/en-US/questions/new/thunderbird-android
Yes, I'm aware it's in beta. I assumed that reports of issues would be useful to the developers.
