I need help pls,this task seems difficult to do!!

[malonykle]

As a student,who concluded highschool(or secondaryschool)recently,I hope to continue my education at a university in the U.S.I learnt that it is nessecary to demonstrate strong ties with my home country during a student visa interview which i would attend at the U.S embassy or consulate in my country.This task seems a challenging one.Therefore,i need to know which method to apply in order to demonstrate or prove these strong ties.I have read several texts and information from different websites on this issue,but i have not gotten a satisfactory solution.I would appreciate your genuine suggestions.Suggestions from people with the visa interview experience and those who have succeeded(people who have been issued visas) would be very welcome and helpful.
Secondly,I want to know the frequently asked questions during U.S student visa interviews(USVIs),and reasonable answers that provide a high chance of getting a student visa.If possible,I would like to know some strategies,skills,etc for success in USVIs.
Thank you.
