I don’t claim to be an expert, but I got myself 3 single entry visas and 1  mutiple entry VISA.  I got my friend a multiple entry VISA after she had been denied twice the past 2 years. I got my dad and my son their first US Visas. And I got a bunch of people  their VISAs under a group appointment.  I am not a travel agent but I would like to share to you what I learned after all these experiences:

1.  Young females, especially single young females automatically have a disadvantage.

2.  Once you were already issued a US Visa (Single Entry) and you have used it, there is a good chance they will grant you another one (probably another single-entry if they still do not trust you).

3.  Time your trip to coincide with a conference that is related to your field or your interest. For instance, if you are a real estate agent here, google real estate conferences or shows in the US and go to the US in time for these events.

4.  It always helps if you are a student at the time of your VISA application.  Although it is not a guarantee that you will get a US Visa.

5.  During the interview,  do not look nervous.  Put it in your mind that it is not a life or death situation.   Relax. 

6. Organize your supporting documents well.  I divided my documents in these categories:

A. Basic Documents

- Passport, Application Fee Receipt, DS156, DS157, Photo, Birth certificate, Consent to Trave (for minors), Marriage Certificate
See US Embassy Guidelines.

B.  Documents showing Reason to Travel

- Invitation Letter for Conferences or meeting

- Very Detailed (if possible, daily) itinerary, Hotel Bookings, List of Places to Visit

- Printout of the conference or meeting webpage and conference schedule

- Membership of local clubs related to the conference you are attending.  For instance, if you are attending a Rotary International Conference, you must show that you have been a Rotarian for at least several months.

C. Documents showing ties to the Philippines

      a. Financial Ties - Bank records, documents showing your assets, ITR

      b. School/Career Ties- Certificate of employment or certificate from the school you are attending. 

These certificates should show how long you have been studying or working.  If you have good salary and if you have a high position, indicate it in your certificate of employment.

If you are an enterpreneur or businessman, bring all the important corporate documents (SEC Registration, ITR, etc) to prove that you have a legitimate, thriving business and that you have a big responsibility in your company.

      c. Family Ties - Marriage certificate or birth certificate of your children

This should show that you need to come back to the Philippines right after your trip because nobody can take care of your children while you are away. This will assuage the fears of the consul that you will be a TNT since there is nobody at home left to take care of your family.

There is no guarantee in getting a US Visa.  The interviewers  are just people and documents can only tell so much.  I will advise that you present yourself and your purpose the best and most-organized way possible. And most importantly. be as honest and transparent as you can be.

Good luck and I hope this post helps.
