hello..i just want to ask whats the real reason why my friend got refused on her application..it was in the letter that she has limited employment prospects in country of residence..i ask some people and they said maybe because of the documents or certificates..im just wondering do the visa officers call the previous employers?i also would like to ask if ever she'll re apply can she omit a work on her employment history,because the work employment she has on that time is under new management and they dont know her anymore..thats why if the visa officer possibly called they cant confirm..thank you so much..
