What visa should I apply for to stay in Thailand for 3 months to visit a friend?

Go to your local thai embassy and get a 90 day visa simple with that you won't have any problems

Why not ask you best mate...or Google it yourself

Probably Kenia pasport (from Nairobi your FB profile says?), of course I might be wrong. If ever you're Kenian pasportholder: You can't enter with visa exemption or Evisa automatically. , Kenia is not Listed on the exemption list. So you need to apply for Visa at the Royal Thai Ambassy in Nairobi and collect all those documents. :Passport: Must be valid for at least 6 months from your arrival date.Passport Photo: A recent, high-quality color photo with a white background.Proof of Travel: Fully paid and confirmed round-trip flight tickets.Accommodation: Confirmed hotel bookings matching your travel dates.Financial Proof: Official bank statements from the past 3 months showing a stable balance.Ties to Kenya: A formal employment letter from your employer or business registration certificates if you are self-employed.Yellow Fever Certificate: This is strictly required for travelers coming from Kenya. Forget 3 months and hope you will have 30 days visa. Overall chances are low. Best maybe contact the Thai Ambassy from Thailand in Nairobi first, before do or book anything.

You will need to obtain a 60 day tourist visa before you travel to Thailand, that can be extended by 30 days at the local Thai immigration office serving the area where you will live in Thailand.

You can't enter visa exempt, you must get a visa.

METV or single entry tourist visa

When do u fly and what passport. Goggle is free. Its still 60days visa exempt on arrival and extend by 30days for small fee. All depends when they change from 60 to 30day soon

You obviously a great writer.

The visa from the thai government

If you’re over 50 and can document either a monthly income equivalent to at least 65,000 baht for the last three months or funds equivalent to 800,000 baht in a bank account, you can apply for a 90-day Non-Immigrant O visa based on retirement.

Otherwise, you can apply for a 60-day tourist visa and then apply for a 30-day extension at a local immigration office. The formal requirements normally include an onward ticket, proof of accommodation (requirements vary), and proof of funds equivalent to at least 20,000 baht.
