recommendation letters

<p>Hello ... I plan to apply to US colleges this year and i happen to have problem with letters of recommendation ... I know even as an international student i should have them otherwise my whole plan would go up to smoke so i would be very thankful if someone could help me ... First of all,would admission offices check and control the letters with professors and teachers who wrote them to check accuracy of letters ? would it be better if i ask professors in US universities who know me to write or my own teachers in high school ? and finally do people who would write letters should be my teachers or if they just know me would be enough?</p>
