I'm pretty sure they'd take you apes back for a price...
Here's part of their stated immigration code:
Senegalese nationality is granted by decree upon application by the party concerned after an investigation.
If the decree is not issued within one year following the application, the application shall be considered to have been rejected.
A formal or implied rejection of the application for naturalization is not subject to appeal.
Article 12 (Law no. 79-01 of 4 January 1979)
No one can be naturalized who does not ordinarily reside in Senegal at the time of filing the application and who has not previously lived there for at least ten years.
The residency requirement shall be reduced to five years for those who are married to a Senegalese woman, who have served for five years in a Senegalese public institution or administration, who have rendered important services to Senegal or whose naturalization is of exceptional value to Senegal.
Ordinary residence is understood as permanent settlement on the territory of the Republic without the intention of later settlement in another State.
For the purposes of the previous paragraph, a stay outside of Senegal by a foreigner exercising a private or public professional activity on behalf of the Senegalese state or of an organization whose activity is beneficial to the Senegalese economy or culture is equivalent to residence in Senegal.
The criteria used for determining the important services or the exceptional value mentioned in paragraph 2 above include the contribution of distinguished artistic, scientific, literary and athletic talents, the introduction of useful industries or inventions, the creation of industrial or commercial establishments or agricultural businesses and, generally speaking, any activity apt to contribute to the country's economic and social development and create jobs.(Law of 26 December 1989).
No one can be naturalized who is not of good character or who has been convicted of a non-political offence and given a custodial sentence not erased by a pardon.
Sentences rendered abroad may be excluded from consideration, in which case the naturalization decree shall require the approval of the Supreme Court.
No person can be naturalized:
1°) who is not deemed to be of sound mind;
2°) who is deemed to be, as a result of his or her state of physical health, a burden or a danger to the community.
The provisions of this article shall not be applied to foreigners who contracted their infirmity or illness while in the service of Senegal or its interests.
Naturalization, in this case, can only be granted on a report from the Justice Minister following consultation with the Supreme Court.
