They got engaged last Valentine's Day. 1 year later, they're still countries apart

Maryam met Mohammadat her nephew's birthday party in Tehran in 2018.

Two days later, they went on a date and the rest was history.

Maryam, who lives in Hamilton, Ont., came back to Canada and the couple began their long-distance relationship.

Last Valentine's Day, Mohammad proposed, and they married in the spring.

However, the lovebirds are still living countries apart Maryam is in Canada as Mohammad waits for his permanent residency(PR) while living in Iran.

They're part of a group of 110 Iranian nationals, 55 couples, who've banded togetherthrough social media over similar experiences with their PR applications. Several couplesshared with CBCNews that being forced to live apart for years has caused fertility concerns andfinancial hardships. Some say they're taking anti-depressants and are even discussing divorce due to strains on the marriage.

Immigration, Refugees and Citizenship Canada's (IRCC) own processing time estimator says spousal sponsorshipshould take about 16 months, but some of those couples say they've been inlimbo foryears.

Meanwhile, protests erupted in Iran and around the world last September, followingthe death of 22-year-old MahsaAminiafter she was arrested by morality police for "unsuitable attire."

Iran has beenexecuting its own citizensas unrest continuesinto the new year. Iranianshave been targetedandsurveilled by the regimeinside and outside the country evenin Canada, where CSISconfirmed ongoing investigations on "lethal threats to Canadians" from Iran. This is why CBC has agreed not to use the couple's surnames.

While Maryam and Mohammad's wait for their spousal PR has been less than a year, they worry their wait will take as long as their fellow group members some waiting more than two years.

"It worries me extremely," said Maryam. "You can't really plan anything for your future."

"Sometimes I had a nightmare that, OK, I should wait for two years to complete my processing?" said Mohammad, speaking to CBC from Iran.

The couple is also waiting for Mohammad's visitor visa application to get approved. He wants to visit her this year to save her a trip toIran during an unstable time.Several Iranian couples told CBC their visas got denied multiple times.
