Answer 1

please read all information necessary to wedding in the Philippines before going there, the first thing you will need is :
Certificate of Legal Capacity to Contract Marriage

Any foreigner who wishes to marry in the Philippines is required by the Philippine Government to obtain from his/her Embassy a "Certificate of Legal Capacity to Contract Marriage" before filing an application for a marriage license. This certification affirms that there are no legal impediments to the foreigner marrying a Filipino (i.e, that the foreigner is already married to someone else).

U.S. Citizens planning to enter and visit the Philippines for 21 days or less do not need a visa prior to travel to the Philippines, provided their passport is valid for at least 6 months and they have a valid return ticket. However, in excess of 21 days, U.S. citizens must either apply for a visa at the nearest Philippine Consular Establishments in the US prior to travel or upon arrival in the Philippines at the Bureau of Immigration(BI), Magallanes Drive, Port Area, Intramuros, Manila, (63-2) 527-3257 or 338-4542. Limited services are also available from numerous BI sub-ports in these cities throughout the Philippines.

Answer 2

You can stay up to 21 days without a visa. If you wish to stay longer you should report to the Philippines Bureau of Immigration. They'll have you fill out a form, submit a couple photos and pay a fee. Then they'll issue you a 59 day extension.

If you overstay, and if you don't get the extension, you'll be stopped on your way out of the country and detained by immigration. You'll miss your flight. They'll fine you and then deport you.

Be sure you understand the process for getting married over there and be sure you have all the necessary paperwork with you.

Answer 3

Visa is not needed to stay in the Philippines for a short period of time even to marry as long as your documents are already complete with both of the couple qualified to marry under the Famili Code of the Philippines.

Answer 4
