Aslum should be filed within one year of entry to the US. Your friend may try going out of US (any country) and then coming back and apply for asylum, given the fact that she has reasonable evidence for applying asylum. asylum is not granted for no reason. there has to be adequate reason of social persecution, fear of persecution, political threats, life threats, extortion etc. You may also wish to check readings in www.uscis.gov or www.anlus.wordpress.com for your help.
