Here are the requirements if you can answer all these questions with a YES then you're eligible:
1. I have a previous B1/B2 Visa that I wish to renew
2. My Visa was issued after July 1, 2007
3. My prior Visa was valid for at least 5 years
4. My prior Visa is still valid or expired within the last 12 months
5. I'm a citizen of the Philippines
6. My prior visa doesn't say " Clearance Received" or "Travel with Employer"
7. I have my passport with my Visa in my posession
8. My Visa was issued on or after my 14th birthday.
9. The last time I applied for a Visa it was approved.
NOTE: The 2Go Courier Service was already paid when you apply for the B1/B2 Visa for $160 so when you are asked where to deliver your Visa the best answer will be your current address instead of a 2Go Center to save on time and effort.
Hope this helps . God bless !!!
