Hello: my sister needs to apply for a Chinese visa, but we have to book our flights now in order to get the best fare. We are interested in going from Seattle to Beijing then to Shanghai, then to Hong Kong and then back to Beijing then back to Seattle. If we buy her air ticket now, can she submit the airline itinerary in order to get at least a double entry to Visa? Will it be assured that she will get at least a double entry L Visa?
