Is registrar remote audit for surveillance or recertification audits allowed?

I have a question regarding the registrar remote audits for the surveillance or recertification audits. IATF does not allow remote audits but I believe the ISO community does. is this correct?

Yes, correct. IATF does not allow any remote audit. 

Also, my question points out to the risk of companies to lose the certification due to Covid 19 - impossibility to be audited and certified. Is any rule as in IATF for extended the current certificate?

‘’IATF Global Waivers and Measures in Response to the Coronavirus’’ the document was published by IATF as revision 03 on 08.06.2020. You can find this document on the website https://www.iatfglobaloversight.org/

Pandemic Faced with this situation, IATF has defined a document called "Global Measures of the IATF in response to the COVID-19". The objective of this document is to define the guidelines so that all the stakeholders of this Certification Scheme must be know how to act to mitigate the impact on the continuity of the audits and certification processes. IATF has granted a 6-month extension to each certificate issued and currently valid. This will be reflected in the IATF Database and will be visible later on in the validity of the certificate.
