Anyone know what is considered sufficient funds per day when applying for a Ghana visa? Thanx

I don't think the amount matters much, but roughly $100 per day should be ok. When my parents applied for a tourist visa to visit me earlier this year, they put down $1000 each per week in the application. They were never asked to produce evidence of this amount in any way.
I assume this may vary, depending on where you're from. A middle aged Scandiavian would never be told to produce evidence of financial strength, while they'll probably look into the bank statements of a young Congolese guy applying for a tourist visa.
