I'm looking to apply for a single-entry visa to China for an upcoming business trip. This trip is crucial for me to engage directly with suppliers and explore potential partnerships. I need to finalize details on my itinerary and the necessary documentation required to ensure a smooth application process. Could you please provide guidance on the steps I should follow to apply for the visa? Also, any advice on the typical processing times and any specific requirements would be really helpful. I want to make sure I have everything in order before submitting my application. Your expertise will be greatly appreciated!
