You can obtain visa at Lome airport, not sure about the price, but should be 10,000 CFA for 7 days. If you need to extend your visa, you must go to Immigrations in Lome. Main office is near Togo cell office and American embassy is nearby. 1 month visa costs 10,000 CFA. You apply for visa there (be sure u have 2 pics), will receive your passport next day. I have good taxi driver there (french speaking only) and a guide - english speaking. If u need more info: muncho@tut.by I'm Bulgarian, have traveled 3 times in Lome.
