I am presently working in Australia on a Permanent Resident Visa and have been invited by a company to go to Beijing for a visit (All expenses Paid by the company) for 3 days only and explore the possibility of working with their Beijing Branch on a Sr. Position and would like to clarify the following;

1. Do I need to apply for a visit visa? Can I apply for a visa upon arrival? How long is the visa processing and how much?
2. My Philippine Passport will Expire in June this year 2011, will that be an issue?
3. What are the requirements that I need to submit and also the company? Thanks.
