falcification of documents

i know someone is now in london. but before she became a citizen there she work there and married to a british even she is already married here in the philippines and not annuled with his filipino husband. Now she is working there as a caretaker for 23 yrs. what case can i file to her, and what are the procedures for her deportation?

NOTHING YOU CAN DO! when citizenship has been approved, they then had a right to obtain UK passport. After that Filipina/Filipino who has obtain UK passport lost the rights to use the Philippine passport therefore, they are no longer under Philippine jurisdiction. Unless they took a dual citizenship which is highly unlikely for most Filipina/Filipino to do!
Also marriage from different country does not count as bigamy because its totally different jurisdiction and before marrying Filipino/Filipina they are required to get a CENOMAR. When Cenomar is produced, marriage happens between Filipino/Filipina and the foreigner. Also since she has been living there for 23 years, Before the approval of her documents during processing the immigration do verify and check each person's records back for 10 years. And if she has been living abroad all that time they then don't dig any records beyond 10 years! the same thing in America. And when passport has been issued, it is highly unlikely to be revoke unless they are terrorist! which is the only case they have to revoke passport from a naturalised person in the UK and the US.

I can see you have your own trouble in life and yet your nosey with other peoples life! try to sort out your own problem first before getting involve with other peoples life! In fact, nothing will happen whoever is that person in London as falsification also 10 years statue of limitation! so if that woman has been in UK for 23 years its highly unlikely for you to get her into trouble! just concentrate on your own problem than sticking your nose in to someone elses business, so KARMA don't come around too often!

if you can find a way to file a case of bigamy in the UK, then that would be the proper case to file

attyLL you obviously don't have an idea with UK citizenship law! The immigration only requires 10 years of records to know the applicants whereabouts and when their citizenship has been granted it will be followed by obtaining British passport there is no way the immigration will believe their appeal simply because the said person has been living in UK for 23 years and she is now a citizen and because she is now a citizen she will be under British jurisdiction unless she took a dual citizenship then Philippines can still interfere.
It is not likely for her British passport to be revoke unless she is a terrorist!

Also have you heard about the Human Rights? They do believe in that! remember the case about Cynthia and David for adultery? Human Rights got involve and gave Cynthia a rights to live in UK rather than being sent to jail for 7 years and her daughter with David will go to her Filipino husband!

A British man who faced a seven-year prison sentence in the Philippines for adultery is being allowed to return to the UK with his girlfriend and baby this week.

David Scott, 37, has had his application for partner Cynthia Delfino to accompany him granted by the Home Office on humanitarian grounds.

Lots of assylum seeker in UK and eventually get approved!
If the case is less than 10 years living in the UK the UK government will require an NBI, CENOMAR, BIRTH CERTIFICATE and other supporting documents FROM HER COUNTRY OF ORIGIN!!!

What if a person legally married in the UK marries someone else abroad or vice versa?

Being married to more than one person at a time is recognised in England and Wales if it took place in a country that allows marriages of this kind (not in the UK) and both parties were legally free to marry in this way. Therefore, if someone legally enters the UK and already has three wives under a foreign law, then they will not be considered to be committing an offence in the UK (provided they do not enter into another marriage ceremony within the UK).

However, this may also mean that someone who is legally married in the UK could potentially marry someone else abroad, as marrying abroad means that the offence of bigamy under UK law is not applicable. However, he or she may be guilty of an offence overseas depending on whether the county he or she marries in criminalizes polygamy.

The Immigration Rules state that a person should not be granted a UK spousal visa if their marriage to the UK sponsor is polygamous and there is another person living with the sponsor in the UK who is also their husband or wife. Therefore, a man married in the UK cannot obtain a spouse visa to bring a second wife into Britain.

if it can be proven that she was first married here in the ph, and then she got married again in the UK, then a case of bigamy against her which is filed in UK, IMO, can prosper.

i don't claim to know about UK immig law, but i do know that the website you copied your post from, http://www.findlaw.co.uk/law/family/other_family_law_topics/500406.html

the website clearly states that UK punishes the crime of bigamy. and if the second marriage was committed in their territory, then a criminal case can prosper

Not entirely true because once the Citizenship has been process they are then British Citizen and protected by the British government unless they take dual Citizenship British/Filipino. This similary case happens to couple of our Aunties one is married to US one is married to UK their husband in Philippines filed a case bigamy in US/UK and the immigration just totally ignore it! simply because the US wife has been married for 37 years and her husband is very poor can't afford to continue the case as it is VERY EXPENSIVE and the UK wife has been married for 20 years and the husband is in jail! I just use the UK website for you to see some examples but BIGAMY does not normally prosper if the marriage took place outside their jurisdiction! But if they remarry again inside US/UK (this is the point where it say the second marriage otherwise marriages outside the UK is not counted Bigamy) if they got married twice inside the UK jurisdiction then they can be sue for Bigamy under their jurisdiction, they have more problems to face rather than getting involve with other countries cases! The immigration problems in US/UK are huge so once the Citizenship has been processed it is not likely for them to revoke the passport unless they are terrorist!
