The query above is something of a "no-brainer" even as it raises some of the most contentious matters in contemporary Jewish life. The simple response to the questioner’s direct inquiry is “No.”
To elaborate, were the individual to convert under Reform auspices, the following is the likely outcome: all Reform authorities and institutions would recognize the conversion as an authentic initiation into Jewish life. Depending on the ritual involved in conversion, many Conservative authorities would accept the person as fully Jewish, and no Orthodox authorities would acknowledge the conversion as valid.
Assuming a conversion takes place within a Conservative setting, it is my understanding that all Reform and practically all Conservative authorities would recognize the conversion, and no Orthodox ones would do similarly. Should the person convert in the Orthodox community, while all Reform and Conservative leaders would accept the conversion, such would not necessarily confer universal acceptance in the Orthodox world, as the matter of whose conversions will receive universal recognition in the Orthodox camp is filled with controversy.
In short the questioner simply must consult with her "home" Rabbi for guidance, and while her goal of full recognition likely is not attainable, it may be the case – depending on her choices and commitment about observance – that a path exists that will result in a conversion viewed by the community or communities she identifies with as authentic and binding.
