Recently, I went from Turkey to Paris to Mexico but mexico denied me entry. They didn't give me any reason. After that they sent me back to Paris but Paris put a stamp on my passport. They put me in a detention center and sent me back to my country.
So I'm worried about it. Can I transit again in Paris or will this stamp create problems for me?
I am from india and I have my UK C unaccompanied child visit multiple-entry visa.
Refused entry stamp (c) paris will it create problem?
You were refused entry into the Schengen Area because you had no valid visa or residence permit after being refused entry into Mexico.
For the Schengen authorities this is nothing more than that a 3rd county national (that requires a visa to enter the Schengen Area) is returning to their home country.
Had you had, after your refusal of entry into Mexico, an airline ticket back to your home country (understandably unlikely), then there wouldn't have been any need do go through a Schengen passport control at all.
France, however, does require an airport transit visa for Indian citizens:
Thus (other than the inconvincence of getting a ticket to your home county from the airside portion of the airport) you were allowed to return to your home country.
For a future application for Schengen Visa, this should pose no problem. Based on what you have written, there was no deceitful attempt to enter the Schengen area.
It may be wise to meantion, in the first application, that a refused of entry did occur.
Sources:
The "(c)" means that you were refused entry to France for the lack of visa (see the Annex V parts A and part B of the Schengen border code).
Since on your way from Mexico you were sent back to France while not having a Schengen visa, the French denied your entry and forwarded you onward to where you came from.
You cannot travel to France (or Schengen) without a valid visa while holding an Indian passport. Indian passport holders also require an Airport Transit Visa for transit through France.
can I take transit again to Paris?
No. You cannot transit or enter France without the appropriate visa. As an Indian citizen, your UK Visitor visa is not valid for Schengen.
will this stamp create a problem for me?
It could, yes. You will have to disclose the denial of entry in any future visa applications that ask about your travel / immigration history.
Note: AFAIK Mexico does allow entry for visa nationals who hold a valid multiple entry visa for the UK. If they denied you entry my guess is you did not fulfil other entry criteria, or perhaps they do not accept the type of UK visa you hold.
