Spouse Visa FLR M to SET M

[fpoptani]

Hello, Have tried looking for this but no success. My wife has at the moment the 2 year probationery spouse visa. My query is from the 2 years is there a minimum period my wife has to be in the UK OR a maximum period of time she is allowed to be away from the UK.
Any advice much appreciated.
Thanks

4.6. Further guidance

There is no specific requirement in the Rules that the entire probationary period must be spent in the United Kingdom. For example, where an applicant has spent a limited period outside of the United Kingdom in connection with his employment, this should not count against him. However, if he has spent the majority of the period overseas, there may be reason to doubt that all the requirements of the Rules have been met. Each case must be judged on its merits, taking into account reasons for travel, length of absences and whether the applicant and sponsor travelled and lived together during the time spent outside the United Kingdom. These factors will need to be considered against the requirements of the Rules.

Don't forget to collect the documents as suggested in the relevant section of the form SET(M) and the KOLL requirements. Absences may affect naturalisation applications.
