am acitizen of democratic republic of congo please i live in uganda how can i get avisa to china for business

You need to submit the following requirements to China embassy in uganda to get a China Business visa:
1. Applicant's passport with blank visa pages and at least 6 months validity left before expiration.
2. Visa application Form V2011A and V2011B
3. One recent passport photo
4. An "Invitation Letter of Duly Authorized Unit" or "Confirmation Letter of Invitation" prescribing the visa validity, number of entries and stay period.
5. your uganda resident permit; if you don't have this, I'm afraid you can only get a China tourist visa in uganda with additional bank statement. If you still want a business visa, you need to go to your home country to get it.
6. Under some circumstances, the applicants may be required to submit a copy of Chinese hotel reservation, return air ticket booking and financial proof.
