What are the requirements and how much do I need to pay for 7days?

Hello there! You just go there for 7 days, so you can apply for a tourist L type. You can ask your friend to issue an invitation letter to you. After, you need to prepare all the required documents: your passport and copy of its data page, the application form attached with a passport-style photo, the business license of your company (copy), recent 6-month bank savings account (no less than 5 million shillings), and the invitation letter from your friend.
It costs 130,000 shillings.
