is it possible to get a 1 year business visa with 90 days entries?

The host company has to send you a multiple entry 'Invitation Letter of A Duly Authorized Unit' or 'Confirmation of Invitation Letter', then you can apply for a 1 year multiple entry visa with 90 days stay duration per entry.

Thank you i received your massage,this is Grace again how can you garante me if i provide all the documents needed as you said you will give me that 1yrs visa with 90days entry.still i would like to know if i can post my passport vis DHL because am in china now that is if i exit to any country then send the passport with all the documents to you if you can out the visa then send it back to me or it is a must i be there that is i present myself to you is it a must.

Ms Grace, this is not the website of the embassy or exit-entry administrative bureau, it is a website of a travel agency. Everyone here can't issue you a 1yrs visa with 90days entry.

I hear that F visa can only be extended twice within Mainland, once you get a multiple entry 'Invitation Letter of A Duly Authorized Unit' or 'Confirmation of Invitation Letter', you can return to your country to apply for 1yrs multiple-entry visa with 90days duration of stay per entry

Hi Bob my problem is similar to ms Grace..how can i get the invitation letter of A Duly Authorized Unit?

kelvin, contact your business partner for help, they may have ways to handle this type of invitation letter from their local foreign affairs or Chamber of Commerce.
