A:Yes, we can send our engineer to your factory for installing, commissioning, training. We have some engineers flying among different countries for after sale service and technical support. As per experience, if everything OK usually 5-15 days is enough. Therefore, before shipment, we need you to prepare invitation letter for visa. However, please be noted that all cost happened for visa, travel, hotel should be paid in advance by customers. In addition, we cannot guarantee each visa is successful.
