Thanks Dear
Just to sum up my understanding
1. Put 800K 2 months before 1st extension
2. Keep it for 3 more months after 1st extension
3. Spend max up 400K For the next 7 months
4. Bump it up to 800K before next extension
5. Repeat
I believe minimum 65K per month remittance is not applicable in this type of Visa
